Carnwath Road Riverside

IntroductionThis chapter covers the feedback comments received during phase two consultation regarding the our preferred site Carnwath Road Riverside. This site would be used to drive the main tunnel to Acton Storm Tanks and receive the main tunnel from Kirtling Street. Carnwath Road Riverside would also receive a long connection tunnel (the Frogmore connection tunnel), which would be driven from Dormay Street. At phase one consultation, our preferred main drive site was Barn Elms. However, following reassessment of potential sites and the tunnelling strategy, Carnwath Road Riverside was identified as our preferred main tunnel drive site and presented at phase two consultation. Barn Elms is still our preferred site to intercept the West Putney Storm Relief CSO (see chapter 6). For further information regarding the proposals at Carnwath Road Riverside at phase two consultation, refer to the Carnwath Road Riverside site information paper. Sections 10.3 (site selection) and 10.4 (alternative sites) of this chapter present feedback on alternative shortlisted sites to Carnwath Road Riverside, which were identified at phase two consultation. These are: Barn Elms (site 1) Feathers Wharf (site 2) Fulham Depot (site 3).

Site selectionA series of sites is required in order to build and operate the Thames Tunnel project. To determine our preferred scheme, a site selection process is being undertaken, using a methodology which was adopted after consultation with the relevant local authorities and statutory consultees. For further information on our methodology and the process we are following, refer to: Site selection project information paper which sets out the process we followed to find and select our preferred sites Site selection methodology paper which details the methodology used to select construction sites along the route of the main tunnel Site selection background technical paper which provides supporting technical information to the Site selection methodology paper such as the engineering requirements for size of construction sites. Site information papers which provide summary information on each of our preferred sites, including the reasons for selecting them Phase two scheme development report which describes how our proposals for the Thames Tunnel project have evolved and provides a detailed account of the site selection process for each of the preferred sites.

The results of the site selection process up to phase two consultation are set in:

10.3.3

In this section, we set out the feedback comments received in relation to the selection of Carnwath Road Riverside as our preferred site, together with our responses. Our responses provide relevant details of the site selection process and its findings up to phase two consultation. Where appropriate we have also identified further work that we have undertaken in relation to our preferred site, such as the preparation of our Preliminary environmental information report (PEIR). As part of the project design development process, we continue to assess how the effects arising from the proposed development can be addressed. The output of our assessment up to phase two consultation is contained in appendix G of the Design development report and our PEIR (volume 13). Where respondents commented on matters in relation to management of construction works, permanent design and appearance or the management of operational effects at Carnwath Road Riverside, these comments are reported in sections 10.5 to 10.7.

Number of respondents10.3.5 During the phase two consultation, respondents were asked to comment on the decision to select Carnwath Road Riverside as our preferred site to drive the main tunnel to Acton Storm Tanks (see question 2 of the phase two consultation feedback form, provided in Appendix M of the Main report on phase two consultation). Table 10.3.1 sets out details of the different groups who responded and were asked to select supportive, opposed/concerned or dont know/unsure. Tables 10.3.2 and 10.3.3 then detail the feedback comments received in relation to this site. It should be noted that not all respondents who provided feedback comments selected supportive, opposed/concerned or dont know/unsure.

Support the identification of a new preferred site since phase one consultation/ the preferred site is more suitable than the site put forward at phase one consultation. Reasons included: - the site has better access and local road infrastructure - it would reduce the number of barges travelling under Putney Bridge, which will reduce the risk for recreational river users - the site is a disused brownfield site adjacent to an industrial park - use of a greenfield site over a brownfield site would be hard to justify - use of this site would not result in the loss of green space; Barn Elms is very valuable recreational resource which is used by a lot of people - there would be less conflict with

Supportive and neutral comments recreational river users - there would be less impact on the Thames Path - the site has better and more reliable river access - The environmental and recreational impact would be lower - Barn Elms has a higher density of residences - fewer residents would be directly affected downstream sites should be favoured over equivalent upstream sites as the spoil has to be taken east - it relocates major tunnelling activities from a greenfield to a partially derelict brownfield site and increases the viability of barge transport by using a currently vacant safeguarded wharf. The preferred site is more suitable than any alternative site. The preferred site is more suitable than any of the shortlisted site(s) - specifically Barn Elms (site 1). Thames Water has taken objections raised at phase one consultation into account in site selection.

Noted. We have considered the comments received at phase one consultation and where possible these have been incorporated into the revised proposals we presented at phase two consultation. Feedback received at phase one consultation is one the factors that has contributed to us changing our preferred main tunnel drive site from Barn Elms to Carnwath Road Riverside. Noted. .

10.3.11

Characteristics which make the site suitable, included: - existing wharves and river access - better quayside mooring facilities for barges - good road access - proximity to strategic road network - being on the inside of a river bend, tidal scouring has created a wider tidal range and deeper channel with capacity for larger barges (850 tonnes rather than 350 tonnes) - the width and height of the navigational span of Wandsworth Bridge, is better than Putney Bridge.

Supportive and neutral comments The site is a cost-effective option, specifically relating to the opportunity to use the river to transport materials and the size of barge that can be accommodated. The site is currently vacant/derelict/available for redevelopment.

The site will be a catalyst for regeneration/redevelopment/improvements to the local area. The site is currently underutilised. Site is of limited value to the local community. Agree with the reasons for selecting the preferred site, as set out in the site information paper. Support the site selection because the project needs to be undertaken. The site is a suitable size and/or has sufficient capacity to accommodate the proposals. It is a brownfield site.

The site is an industrial site. Proposals are compatible with existing uses in the vicinity of the site, which includes industrial uses.

Noted. Effect on residents was one of the considerations taken into account as part of our site selection process as well as the ability to mitigate likely significant effects. Noted. Open space is one of the considerations taken into account as part of our site selection process. The purpose of consultation is to explore as fully as possible what those with an interest in the project think about our proposals. We will have regard to comments received from both technical and non-technical consultees. Your comments are noted.

Supportive and neutral comments Road. Other comments included: - shocked and concerned about the cynical stirring up of concerns amongst local residents and the knee jerk reaction from the council - should not hold the project back as a consequence of 'NIMBY' protestors - it is selfish to only consider personal interests by opposing a project that will benefit the whole of London.

Qualified support for the preferred site included: - any site is acceptable subject to appropriate mitigation

EH, 9434LO, 7777, 7975, 8098, 9253

Since selecting Carnwath Road Riverside as our preferred site, we have begun assessing the likely significant effects that may arise as a result of the works as part of an environmental impact assessment. This will set out measures necessary to mitigate any likely significant effects that are identified. An Environmental statement, which records the findings of the environmental impact assessment, will accompany our DCO application. The initial environmental assessment work that has been carried out on the project is contained within the PEIR (volume 13), which is available on our website. As part of the phase two consultation, we have also sought feedback on the potential likely significant effects arising from our proposals and how the effects will be mitigated. Where possible, we will take feedback comments into account as we develop our proposals. . Refer to paragraphs 10.5.56 and 10.7.47 for our response to this feedback comment. We are currently considering our design proposals for the site and will consider how we can take your comments into consideration. Refer to paragraph 10.5.353 for our response to this feedback comment. Refer to paragraph 10.5.341 in relation to highway improvement works. With regard to provision of environmental information, we consider that we have undertaken a thorough and comprehensive consultation exercise. As part of this, we carefully considered the information we made available at our phase two consultation to ensure that consultees had sufficient information to respond to the consultation. Information of key likely significant environmental effects was contained in the Carnwath Road Riverside site information paper with further details contained within the PEIR (volume 13) and the draft CoCP. We are confident therefore that the information we have provided is sufficient. Refer to paragraphs 10.5.141 and table 10.5.213 for our response to this feedback comment.

- odour must be controlled - ventilation shafts must be incorporated into future development - the river must be used to transport excavated material and bulky goods - subject to confirmation that Thames Water will not require any highway improvements and/or sufficient environmental information to enable others to make this assessment

- require additional information from Thames Water to demonstrate that there will be no unacceptable noise, vibration and socio-economic impacts.

Objections, issues and concerns

Do not support the specific location of the site. Should use/consider an alternative site specifically one in a less densely populated or residential area. There are other more suitable alternative sites available in the local area, including several south of the River Thames, Wandsworth Park, between Putney and Hammersmith Bridge, Battersea Power Station, industrial sites, less costly options, and other unpopulated sites. Alternative sites have not been properly considered.

Site selection has not incorporated comments and objections from phase one consultation or interim engagement.

Following phase one consultation, we considered the comments from phase one consultation, along with feedback from on-going engagement, new information and undertook further technical work. This triggered a review of all potential main tunnel sites between Hammersmith Bridge and Albert Bridge. The result of this review and assessment (which was based on our agreed site selection methodology) was that we changed our preferred main tunnel drive site from Barn Elms to Carnwath Road Riverside. Therefore, it is difficult to maintain that we did not consider feedback to phase one consultation because this resulted in a number of changes to sites, use of sites and our drive strategy in the western end of the main tunnel. For further details of how we have taken account of the feedback received at phase one consultation and interim engagement refer to our Report on phase one consultation and Interim engagement report. We considered the comments from phase one consultation, along with feedback from on-going engagement, new information and undertook further technical work. As set out in appendix G of the Phase two scheme development report, the following reasons triggered our decision to review whether Barn Elms remained the most suitable main tunnel drive site. These were: - We were aware that LBHF had changed the planning policy designation at the Hammersmith Pumping Station site from mixed use

10.3.37

The preferred site put forward at phase one consultation, Barn Elms, is more suitable because: - the scale and type of impact is more acceptable - it would have less impact on residential amenity and the local community - less impact on business

Objections, issues and concerns - it will not hold back wider regeneration - the site is less physically constrained in terms of river access, contamination and size - it is a cheaper option - recreational impacts can be satisfactorily mitigated - the site can be easily restored following completion of construction - local road infrastructure is more suitable and traffic disruption would be minimised - combined sewer overflow (CSO) interception and main tunnel drive sites should be combined - there is no reasonable reason why this site cannot be used. Reasons for changing the preferred site since phase one consultation are unclear/unjustified/unsatisfactory. In particular: - too much weight has been given to the 'greenfield' and Metropolitan Open Land (MOL) status of the site - local planning policies have been misapplied - the temporary impact on a greenfield site/MOL is acceptable, as acknowledged by Thames Water - the scale of impact on the local community resulting from the use of Carnwath Road is unacceptable, vs environmental/recreational impacts at Barn Elms - the issues relating to site constraints such as foreshore depth apply to both sites - the scale of impact associated with using Carnwath Road and its feasibility as a main drive site has not been fully identified/ assessed

Our response to residential. As a result of this, at the time of our review a new planning application for a residential development on the part of the site which excluded Hammersmith Pumping Station had been submitted. This planning application has now been approved and construction works have commenced. - because of strategic design developments, the long connection tunnel between Hammersmith Pumping Station and Acton Storm Tanks, which needed to be the same width at the main tunnel, and therefore the main tunnel needed to be extended to Acton Storm Tanks. - review of tunnelling strategy for the western part of the main tunnel. - further technical work on barge movements at Barn Elms confirmed that only 350 tonne barges could be used to transport materials by river. Due to the short tidal window, this limited the amount of material which could be transported by river. The reduced width of the River Thames at this location also increases the potential for conflict between barge operators and recreational users of the River Thames. - comments from phase one consultation on the effects of using Barn Elms as a main tunnel drive site. - changes in the engineering site size assumptions which underpin the search for suitable sites. As a result of a review of possible sites, Barn Elms and Carnwath Road Riverside emerged as the two most suitable sites. We consider that Carnwath Road Riverside is more suitable than Barn Elms because: - Carnwath Road Riverside is a brownfield site while Barn Elms is a greenfield site. - Carnwath Road Riverside includes a safeguarded wharf and has much better river access for transportation of construction materials, using significantly larger barges (800 1000 tonne rather than 350 tonne) than can reach Barn Elms. - at Carnwath Road Riverside, there would be less conflict with recreational users of the River Thames than at Barn Elms. - Carnwath Road Riverside has better direct access to the public road network and links to the strategic road network. In contrast, at Barn Elms there would be a need to construct lengthy temporary access roads across the Barn Elms playing fields to local roads. - use of Carnwath Road Riverside is less disruption to the Thames Path than at Barn Elms. The Thames Path is already diverted around the site at Carnwath Road Riverside. - use of this site will have less impact on the natural and built environment in terms of planning policies and designations whereas using Barn Elms as a main tunnel drive site would affect MOL, the site is adjacent to a SSSI (Wetlands Centre), would affect Barn Elms Playing Fields and would necessitate need to demolish local community boating facility etc. Further information including responses to the detailed points raised is contained within appendix G of the Phase two scheme development

Objections, issues and concerns - the criteria and reasons for rejecting Barn Elms need to be made public - the reasons for changing the preferred site (brownfield site, opportunities for river transport and reduced impact on recreation) are not sufficient to justify the change of site - Thames Water has admitted that the use of Carnwath Road would be more costly and disruptive - the increased cost of using Carnwath Road cannot be justified - Thames Water has breached the principles of lawful consultation

Our response report. The criteria and reasons for rejecting Barn Elms have been made public. Refer to paragraphs 10.3.1 and 10.3.2 for further details. We disagree. These are important considerations and cannot be dismissed as being irrelevant.

See paragraph 103.3.57 for our response to these feedback comments.

- Carnwath Road Riverside was explicitly identified and rejected at phase one consultation.

10.3.39

One of the shortlisted sites is more suitable. Specifically, Feathers Wharf (site 2) is close to a rail line and next to waste transfer site with existing barge facilities. The ventilation column could be easily accommodated, and the River Wandle could accommodate a piled deck platform over the river as a temporary raised structure to provide additional space. The site already suffers from odour associated with the waste transfer station. The site selection methodology is

12539, 13395, 7673, 7968, 9461

This is not a matter for site selection. However, in devising and carrying out our consultation strategy, we met the requirements of the Planning Act 2008 and have had regard to the Department for Communities and Local Government guidance on pre-application consultation. We do not consider therefore that we have breached the principles of lawful consultation. At phase one consultation we identified two main tunnel intermediate sites that covered Carnwath Road Riverside. At this point, from a technical perspective we said that a main tunnel drive site needed to be at least 20,000m2. We listened to concerns raised at phase one consultation and re-checked our engineering assumptions. We found that where we were constructing in clay, we could use smaller sizes that previously identified. As a result, we reviewed and re-assessed all sites between Hammersmith Bridge and Albert Bridge; we found Carnwath Road Riverside to be suitable in this main tunnel zone. We then rechecked our drive options for the western section of the main tunnel. When we compared the different drive options using Barn Elms and Carnwath Road Riverside, we found Carnwath Road Riverside to be the most suitable site. For further details, refer to chapter 6 and appendix G of our Phase two scheme development report. Our re-assessment of sites prior to phase two consultation and our review of phase two consultation comments do not support the use of Feathers Wharf as our preferred site. Feathers Wharf is less suitable than our preferred site because it is too small to accommodate all the works and no viable partner site could be identified. Refer to appendix G of the Phase two scheme development for further details of our assessment.

Objections, issues and concerns incorrect/flawed/unjustified. In particular: - further in-depth impact analysis is required before Thames Water can make an informed decision - the relative merits of different sites need to be quantified - factors should not be equally weighted - site selection is a subjective Thames Water decision

Our response extensive site selection process as set out in the Site selection methodology paper that is available on our website. This methodology was agreed with key stakeholders, including potentially directly affected local authorities, prior to its use. The paper explains how environmental, planning, engineering, property and community considerations were taken into account in the site selection process. The site selection methodology does not include a quantitative scoring or weighting element. Such an approach is not considered best practice, and this was agreed with stakeholders when consulting on the draft methodology.

Whether a site is brownfield or greenfield/open space was taken into account along with other considerations as set out in the Site selection methodology paper. In general, main tunnel sites will be located on land due to a range of engineering constraints and requirements. Only where it has proved difficult to identify suitable land-based sites, have we explored the potential for siting main tunnel sites wholly or partially within or on the foreshore of the River Thames. Further information can be found within the Site selection background technical paper, which is available on our website. We can confirm that apart from the construction of a campshed to facilitate use of barges at this site, we are not proposing to construct within the foreshore. The campshed design and construction will mitigate any likely significant environmental effects. The planning status of a site was taken into account along with other considerations as set out in the Site selection methodology paper. A professional judgement was then made in relation to the impact on the planning status of that site and this was balanced against other considerations identified in the Site selection methodology paper. It should be noted that even if sites have been allocated or have secured a planning permission, that does not preclude the use of the site. Other factors such as whether the planning permission will be implemented need to be considered Even then, it may be possible for construction work to be phased so that both the approved development and the Thames Tunnel project can be constructed. Sites located within designated regeneration areas do not necessary preclude the use of the site as our proposed use in many cases can be complementary or beneficial to some of the regeneration aims.

Our response We are aware of the allocation within the adopted Core strategy for residential development on both Whiffin Wharf and the Carnwath Road Industrial Estate and of Hurlingham Wharfs safeguarded wharf status. Consequently, we have organised the layout of our proposed permanent works such that there will be no effect on the Carnwath Road Industrial Estate, however, some of Whiffin Wharf will be occupied by our main tunnel shaft and several above ground structures permanently, which may prevent the use of the entire site for future development. In addition, we are providing for a significant area of permanent public open space west of our permanent works and for an area for future development. We therefore believe that the area sterilised by our proposed works is minimised and following completion of our temporary works the development aspirations for this area can proceed. We are currently considering our design proposals for the site and will consider how we can take your comments into consideration. We have considered the effect on local area and businesses as part of the site selection process, the results of which concluded that Carnwath Road Riverside is the most suitable site.

Carnwath Road Riverside is an industrial site. We recognise that our preferred site is within close proximity to residential housing. As part of the project design development process, we continue to assess how the likely significant effects arising from the proposed development can be addressed. The output of our assessment up to phase two consultation is contained within appendix G of the Design development report and our PEIR (volume 13). Carnwath Road Riverside is a partially vacant site. In identifying our preferred sites, we have followed the methodology set out in the Site selection methodology paper. Having considered the issue raised, we are confident that the basis on which we identified the site as a preferred site is consistent with our site selection methodology. The main tunnel search area and tunnel alignment generally follows the River Thames. This is an efficient route to connect CSOs on the north and south side of the river, minimises going under buildings and allows use of river transport during construction. In addition to the locational constraints for main tunnel sites, the sites need to fulfil other engineering requirements and planning, environment, planning and community considerations. Given that we are searching for sites within complex built up areas of central London and given the requirements that the sites need to fulfil, we did not consider it appropriate to exclude sites based on their use when compiling our longlist of sites. Proximity to residential areas and the likely significant effect of the proposals on residential amenity was taken into account along with other considerations as set out in the Site selection methodology paper.

10.3.46 10.3.47 10.3.48

Site selection should prioritise use of vacant sites. Site selection should avoid sites in residential and/or densely populated areas. Impact on residential amenity should be considered as part of the site selection process. Site selection needs to be reconsidered and should focus on less residential areas.

Our response We recognise that our preferred site is within close proximity to residential housing. As part of the project design development process, we continue to assess how the likely significant effects arising from the proposed development can be addressed. The output of our assessment up to phase two consultation is contained within appendix G of the Design development report and our PEIR (volume 13). Proximity to sensitive receptors including schools and nurseries was taken into account along with other considerations as set out in the Site selection methodology paper. We recognise that Thomass Fulham School in particular is within close proximity to our preferred site. However, as set out in appendix G of the Phase two scheme development report, we consider that Carnwath Road Riverside is the most suitable site and that likely significant effects on community facilities can be mitigated.

10.3.50

Site selection should avoid sites close to sensitive receptors, including: - schools and nurseries; there are 17 schools and four nurseries within 1,500 metres of the site - sheltered housing.

Our response Community (which includes socio-economic issues) and environmental considerations have both been examined (alongside engineering, planning and property considerations) as part of our site selection process. No one issue takes precedence over another, however all relevant factors are examined by the project team and a judgement made as to the suitability of a site, taking into account all relevant considerations. We believe that our assessments, which have been carried out in accordance with the Site selection methodology paper, are comprehensively explained in appendix G of the Phase two scheme development report. Refer to paragraph 10.3.47 for our response to this feedback comment.

10.3.53

Selection of this preferred site has been poorly justified/inadequately explained. In particular: - the benefits of site selection do not outweigh the nuisance that it will cause - no explanation of why a residential area is considered suitable - the site will be more costly and disruptive to local residents - use of this site would result in unnecessary cost - would like further information regarding the relative costs and benefits associated with using this site - site selection has been poorly thought through - unclear why the site now meets the site size criteria when previously it was too small - reasons why the site was unsuitable at phase one consultation.

Refer to paragraph 10.3.53 for our general response to this feedback comment. In relation to the specific points raised, refer to our responses below. We do not agree. The reasons why this site is needed are set out in chapter 6 and appendix G of Phase two scheme development which is supported by our Engineering options report and Site selection background technical paper. Carnwath Road Riverside is a previously developed site. The National Planning Policy Framework defines previously developed land as land which is or was occupied by a permanent structure, including the curtilage of the developed land (although it should not be assumed that the whole curtilage should be developed) and any associated fixed surface infrastructure. This excludes: .... land in built-up areas such as private residential gardens, parks, recreation grounds and allotments; and land that was previously-developed but where the remains of the

Our response do not consider that the previous uses of the site present development constraints. Cost is one of the considerations that inform site assessments, but it is not an overriding factor that outweighs all other engineering, planning, environmental, community, property and wider economic considerations. High acquisition costs alone would not outweigh positive considerations such as use of brownfield land, conformity with planning policy, and the ability to construct/operate the proposed works on the site. Equally, a low value site would not result in a site becoming our preferred site, if there were significant planning, engineering, environmental or community concerns associated with its use. In determining our preferred site, we made a balanced judgement taking planning, environment, engineering, property and community considerations into account. The Site selection background technical paper, which accompanies the Site selection methodology paper, specifies the sizes for CSO and main tunnel sites. We have used these criteria to select our preferred sites. Carnwath Road Riverside is therefore an appropriate size to accommodate our proposals. We note that following selection of Carnwath Road Riverside as our preferred site, the Secretary of State has issued an Article 25 Direction that prevents the determination of all planning applications that affect this site. We believe that this direction reinforces the conclusions of our site selection process. Refer to Site selection background technical paper for further details on appropriate site sizes for main tunnel sites. Our site selection process has had regard to possible likely significant effects on the local area and community, and the environmental impact assessment process will undertake further assessment and recommend any necessary mitigation measures. The environment and community assessments undertaken as part of site selection considered the number and nature of sensitive receptors as well as possible likely significant effects from traffic and construction works including noise, air quality and visual impact. We also considered likely significant effects on employment uses and possible conflict with planning policy that seeks to protect local amenity. Accordingly, we consider that the scale of possible likely significant effects on the local area and community has been adequately considered. For further details on the results of the site selection process, refer to appendix G of the Phase two scheme development report. In identifying our preferred sites, we have followed the methodology set out in the Site selection methodology paper. Political pressure has not played any part in our site selection process.

10.3.57

The cost of using the site is too high/not cost-effective. Specifically, the cost of using this site is higher than using Barn Elms. Thames Water has a duty to minimise costs since they will be passed on to Thames Water customers.

The site is too small and does not have sufficient capacity to accommodate the proposals. Specifically: - in order to accommodate the construction works, an industrial estate would need to be demolished - the site would be 50 per cent too small without two compulsory purchases.

The scale of effects on the local area and community resulting from the selection of this site is unacceptable/ has not been properly considered.

Our response We consider that we have undertaken a thorough and comprehensive consultation exercise. As part of this, we carefully considered the information we made available at our phase two consultation to ensure that consultees had sufficient information to respond to the consultation. Details of sites considered as part of the site selection process are described and illustrated throughout the phase two consultation material including the site information papers which provide an overview with the detail in appendix G Phase two scheme development report. We are confident therefore that the information we have provided is sufficient. The main tunnel search area and tunnel alignment generally follows the River Thames. This is an efficient route to connect CSOs on the north and south side of the river, minimises going under buildings and allows use of river transport during construction. In addition to the locational constraints for main tunnel sites, the sites need to fulfil other engineering requirements and planning, environment, property and community considerations. Given that we are searching for sites within central London and given the requirements that the sites need to fulfil, we did not consider it appropriate to exclude sites based on their use when compiling our longlist of sites. In relation to Carnwath Road Riverside, as set out in appendix G of the Phase two scheme development report, while we recognise that our proposals may have a potentially adverse effect on businesses operating out of the eastern part of the site, the other benefits of this site outweigh this consideration in this case. Any existing businesses would be assisted with relocation in line with our published A guide to the Thames Tunnel compensation programme. We consider there will be no likely significant effect on Hurlingham Retail Park. As set out in the Needs report, the Thames Tunnel project will address the water quality, ecological, aesthetic and health issues identified as supporting the need for the project. The Thames Tunnel project will also provide additional benefits for the sewer system, in terms of improving the operation and maintenance of the sewer network, and providing greater robustness and flexibility for the future impacts of population growth and changes in the pattern of rainfall due to climate change. Using a site for the Thames Tunnel project does not preclude the site being used for other uses once construction of the project is complete. The footprint of the permanent works required for the operation of the Thames Tunnel project is significantly smaller than the space required during its construction. The area not permanently required could be used for other uses that obtain planning permission. Refer to paragraph 2.2.32 for our response to feedback comments related to need and solution. It is incorrect that sites to construct the main tunnel have to be located at sites to intercept CSOs. We need to identify both types of site.

10.3.62

Site selection should avoid commercially established areas; in this particular instance established businesses would need to be relocated which would have significant impacts on current occupiers of the site. Furthermore, proposals may have an adverse impact on the Hurlingham Retail Park.

Our response

As set out in the Carnwath Road Riverside site information paper and appendix G of the Phase two scheme development report, we consider that Carnwath Road Riverside is the most appropriate site because it is a brownfield site. The presence of wharves at this site combined with the width of the River Thames at this point would allow the use of larger barges to remove material excavated during construction of the main tunnel. There would be much less conflict with recreational users of the River Thames than at Barn Elms. Following the feedback from phase two consultation, we have considered the alternative sites suggested (see section 10.3 of this chapter) and the comments received in relation to site selection. As a result of this process, we still consider that Carnwath Road Riverside is the most appropriate site. Construction of the tunnel in this location is not expected to compromise the wider regeneration of the area or future redevelopment of the site. Landowners may have a statutory entitlement to claim compensation for the diminution on the value of their property due to the construction of the tunnel. Landowners include the council or local housing associations that own social housing in the area. In addition to the statutory process, we have published an Exceptional hardship procedure which sets out how we will assess claims from householders who contend that they are suffering exceptional hardship as a result of being unable to sell their property because it is potentially impacted by the currently published Thames Tunnel project proposals. We have also published A guide to the Thames Tunnel compensation programme which sets out details of compensation that would be available arising from damage or loss during construction, for required protection measures, and for compulsory purchase.

- Thames Water should confirm that all three other shortlist sites are still under active consideration and considered viable replacements to the preferred site - even at this stage, the proposals are having a negative effect on the local area - if Carnwath Road Riverside is selected, only the more privileged people will leave the area; the people who will remain will be those who can't afford to move house.

For further details on the results of the site selection process, refer to appendix G of the Phase two scheme development report.

The shortlisted site Barn Elms (site 1) is See annex C of this report unsuitable for the proposed use because: - wrong to use a greenfield/ MOL site when there is a brownfield alternative - site has high ecological value and is close to a Site of Special Scientific Interest (SSSI) - site offers environmental benefits, including urban cooling and reducing surface runoff which would be affected if the site was used for the project - playing fields are protected by various indicatives, such as the Queen Elizabeth II Fields in Trust and planning policy - site has a high recreational value, both for land and river based sports clubs, informal recreation, the Thames Path and National Cycle Network - impact on the Oxford and Cambridge Boat Race - barge size restrictions would increase the number of barge movements - the local road infrastructure is unsuitable for heavy construction traffic and existing traffic would be exacerbated - proximity to residential areas and associated impact on residential amenity - exacerbation of existing air pollution issues and associated impact on residents health - there is a high pressure gas pipe running across the playing fields The shortlisted site Fulham Depot (site 3) is unsuitable for the proposed use because of potential impacts on adjoining businesses, including the Porcelanosa show room on the corner of Wandsworth Bridge/ Townmead Road.

Reasons a better engineering solution. The core of the site is a safeguarded wharf and therefore provides good opportunities for use of the river to transport excavated material, which will reduce effects on local roads. The opportunities for barge use are less constrained than at Barn Elms. The site also has direct road access to major arterial routes. The site is earmarked for regeneration in a less residential area and it is considered that it will cause less disruption. It would not result in loss of recreational space and would create less disruption for recreational river users and the regular rowing races. There would be no impact on the Thames Path since it is already diverted and the site would have minimal impact on the environment. Permanent structures/landscaping could improve the site. The site is open space/greenfield which is preferable to a brownfield site. Respondents also query the robustness of conclusions regarding planning policy and undertaking temporary construction works on Metropolitan Open Land. It allows the CSO interception and main tunnel site to be combined, which is supported in Thames Water's site selection methodology. The impact on the natural environment does not outweigh the impact on local residents at Carnwath Road Riverside. The move away from Barn Elms is politically motivated. There would be reduced impact on local residents, since they are located further away from the site. This site would also have less impact on local

Reasons Respondent ID businesses, schools and vulnerable communities. It is a larger size which will make construction easier, and would mean lower construction-related costs and require a shorter period of construction works. Despite the loss of open space, recreational use of the Barn Elms Playing Fields would not be affected. There is better road access/less local road congestion. Do not consider that river access is much reduced in comparison to Carnwath Road Riverside. Any restrictions that do exist can be overcome. It will be easier to restore the site once construction works are complete and the London Wetland Centre provides interim mitigation. It will be easier to mitigate the impact on recreational users. Any permanent structures would have reduced visual impact in comparison to Carnwath Road Riverside. It is next to a waste transfer site and industrial estates. The River Wandle could easily accommodate a piled deck platform over the river as a temporary raised structure in an industrial site to give additional space. The site has existing river access and is close to a rail line, both of which would reduce the need to use road. Any permanent structures would have less of a visual impact. 7673, 7741, 8124

Feathers Wharf.

Feathers Wharf is only big enough to be used as a main tunnel reception site. We have explored whether it would be possible to expand the size of the site so that it could be used as a main tunnel drive site. To do this, decking would need to be constructed over the River Wandle which would have significant effects on this water body. The site does not have barge access and therefore it would not be possible to remove excavated material by water. Use of barges is an important consideration when identifying suitable main tunnel drive sites due to the large amount of material that needs to be removed. The site access is also constrained and there is high density residential housing adjacent to the site. This means that, based on our preferred drive strategy (ie, drive the tunnel from Carnwath Road Riverside to Acton Storm Tanks) the site cannot be considered as an alternative to Carnwath Road Riverside since it is not a suitable size. For further details refer to appendix G of the Phase two scheme development report. We have identified other shortlisted sites. Based on our assessment of these sites, we consider that they are less suitable. Appendix G of the Phase two scheme development report sets out in detail the other sites considered and the reasons why we consider the sites less suitable.

Our response We do not consider that Acton Storm Tanks is appropriate as a main tunnel drive site. This is because large volumes of excavated material are produced at main tunnel sites and there are no viable river or rail options for transport of excavated material in the vicinity of this site. This would therefore require large number of heavy goods vehicle (HGV) movements which we do not consider appropriate due to the environment effects that would arise. Therefore, we consider that Acton Storm Tanks is only suitable as a main tunnel reception site. Refer to paragraph 2.5.18 for our response to these feedback comments.

Kirtling Street.

It is a large brownfield/derelict site in an industrial area, where redevelopment is already planned. It would also provide an appropriate site for the long tunnel drive to Acton Storm Tanks, removing the need for Carnwath Road Riverside. Thames Water is already considering using this site. The site is in a less residential area so would have fewer impacts on residential amenity and educational facilities. It would also not result in direct loss of employment or employment space which meets an identified need. Any affected businesses could also be relocated. The site also has good river and road access and, although a diversion of the Thames Path is required, it would not alter the point at which direct access along the river is resumed. The site is located on the River Thames, where 24-hour access would go unnoticed. Overall, works would result in less environmental impact due to the existing poor environmental quality of the area. It is a large brownfield/derelict site, which is further away from residential properties. The site has good road and water access with existing wharfage. Any permanent structures would have less of an impact. All excavated material could easily be handled at this site. Generally larger brownfield sites are in mostly non-residential areas and so would cause less disruption.

We did identify and consider this site but it did not progress beyond the draft shortlist stage of the site selection process due to multiple constraints, including planning and environment designations within a residential area where there is a lack of alternative recreation facilities. We did identify and consider this site but it did not progress beyond the draft shortlist stage of the site selection process due to multiple constraints, including environment and heritage designations and in particular the scheduled ancient monument. We did identify and consider this site. However, it did not progress beyond the draft shortlist stage. This is due to multiple constraints, one of which is that the site is upstream of Hammersmith Bridge so has severe river and navigational limitations. On this basis it was not considered suitable as a main tunnel drive site. We did identify and consider this site. The site is currently used by the Western Riverside Waste Regulation Authority who manages waste delivered to it by LBHF, the London Borough of Lambeth (LBLam), LBW and the Royal Borough of Kensington and Chelsea (RBKC). This is a key waste infrastructure site that is well used and is therefore not available for use as part of the Thames Tunnel project. We did identify and consider these sites. Both sites have planning permission for high density residential developments which are under construction, so are not available for use as part of the Thames Tunnel project.

Our response In developing our site selection methodology, we reviewed whether it would be technically possible to construct a main tunnel site within the foreshore of the River Thames. As set out in the Site selection background technical paper, main tunnel sites must be on land, because the size of the main tunnel drive sites required during the construction phase means it would not be practical to accommodate them on platforms entirely in the river. Once the tunnel is operational, the shaft would be used to provide access to the tunnel network. The tunnel must also satisfy health and safety requirements regarding safe egress from the tunnel by the workforce in an emergency. It becomes more difficult to satisfy these requirements when sites are located within the river. It is therefore not feasible to use a site on the foreshore at Putney. Falconbrook Pumping Station has been identified through the site selection process as being suitable as a CSO interception site. A smaller site is needed for CSO interception and therefore the suggested site is not large enough to accommodate works associated with a main tunnel site. In relation to using the Putney Hospital grounds for a main tunnel site, we considered that this was unsuitable because it would require the main tunnel to be brought inland instead of being located under the River Thames, resulting in the tunnel running under many residential properties/other buildings. The site is also located between a residential area and Putney Lower Common, so we do not agree that there would be no disruption to the local community. As a result of these two factors, we do not consider this site suitable. Areas near the disused Putney Hospital were considered as CSO sites to intercept the West Putney Storm Relief CSO, but were not considered suitable for main tunnel sites. For further details on our assessment of the West Putney Storm Relief CSO, refer to appendix C of the Phase two scheme development report. This site has been considered. In appendix G of our Phase two scheme development report this site has been referred to as Land at Lots Road, Chelsea Harbour (ref no S86HF) and the land north of Chelsea Harbour Drive forms part of the Lots Road Power Station planning application site. The site was rejected as a main tunnel drive site because it was a development site, where development had or was soon to commence and this planning status would increase acquisition costs to an unacceptable level. Furthermore, it is understood that development has commenced on site and there is a current application (ref 2011/03122/FUL) that seeks consent for a reduction in the total number of residential units to be provided from 382 to 297. In addition, we need to build a 1.7m step into the main tunnel upstream of a new National Grid cable tunnel which is being constructed beneath the Carnwath Road Riverside site. At this site is downstream of Carnwath Road Riverside it does not enable us to incorporate the 1.7m

Our response step into the tunnel and thereby would present us with significant difficulties in designing a vertical alignment that would meet the hydraulic requirements of the tunnel and maintain satisfactory clearances to other tunnels. We have considered a significant number of sites on both sides of the River Thames between Hammersmith and Albert Bridges as set out in appendix G of the Phase two scheme development report. The sites that as a result of our assessment were considered suitable, were presented at phase two consultation for comment. Sites upstream of Hammersmith are not considered suitable due to river navigation and barging constraints. In relation to narrowing our search to particular types of sites, the methodology requires that we do not prejudge where or what type of site we may find by excluding certain sites or emphasising certain factors above all others. We have therefore looked at sites in non-residential areas and greenfield sites.

It is a non-residential area with good road access, so would have less impact. Sites along the river would allow river transport. The preferred site is too close to major roads. The site should be located where it will affect the fewest people and cost the least. Sites south of the river are less disruptive to the local community and have better road access.

Outside of south-west London and not within central London.

The suggested alternative sites are outside of the area defined by the Site selection methodology paper. This is because the start of the main tunnel in west London must be in the vicinity of the most western CSO that we need to intercept. The most western CSO that we need to intercept is Acton Storm Relief CSO. Areas which are west of this point are not within the scope of the Thames Tunnel project. In addition, the suggested site/area is upstream of Hammersmith Bridge, which means there are severe barging and navigational constraints in relation to using the River Thames to transport excavated material and materials for the construction of the main tunnel. Use of river transport is one of the considerations used for identifying suitable main tunnel sites. For further information refer to the Site selection methodology paper and Site selection background technical paper.

It is the responsibility of Thames Water (and their consultants) to identify sites. Not the role of consultees to suggest alternatives sites, we merely oppose bad options.

Management of construction works

This section sets out feedback comments received during the phase two consultation in relation to the management of construction works at Carnwath Road Riverside. This includes the identification of site specific issues arising from construction activities and proposals to address the effects of these issues. During the phase two consultation, respondents were asked whether the site information paper had identified the right key issues associated with Carnwath Road Riverside during construction and the ways to address these issues (see questions 4a and 4b of the phase two consultation feedback form, provided in appendix M of the Main report on phase two consultation). The first part of question 4a and 4b asked respondents to select agree, disagree or dont know/unsure. Where respondents completed this part of the question, the results are set out in tables 10.5.1 and 10.5.2. Tables 10.5.3 to 10.5.46 detail the feedback comments received in relation to this site. It should be noted that not all respondents who provided feedback comments confirmed whether the right issues and the ways to address those issues had been identified.

Respondent ID 7795 8528, 8884 No. 1 2 Our response The key issues in the Carnwath Road Riverside site information paper are intended to provide a broad overview of likely significant effects and key issues associated with the site during construction. It is not however an exhaustive list. A more detailed description of possible likely significant effects and the methodology through which they have been identified is and assessed is provided in other technical reports, including the PEIR (volume 13) Phase two scheme development report and site selection methodology and background papers. We are undertaking an environmental impact assessment, which will include a comprehensive assessment of likely significant effects arising from the proposals. The findings of the assessment, together with any recommendations for mitigation, will be available as a part of the Environmental statement that will be submitted with our DCO application. Providing a balanced analysis in our consultation material was imperative and we do not agree that the material was biased in our favour, inaccurate or misleading. All the material presented contained necessary information for consultees to understand our proposals, make their own judgements and provide feedback over the consultation period. An overview leaflet was included with the notification letters sent to community consultees in the vicinity of our preferred sites. The overview leaflet summarised our proposals and described likely significant effects, including at our preferred sites, in clear, accessible and non-technical language. The information provided also made it clear how consultees could find more information on the project including on our website, at one of our exhibitions or by calling a dedicated phone line. In total we sent 129,515 letters, overview leaflets and language line information sheets to residents with an interest in the project. However, given the volume and size of documents, direct delivery of all documentation was not feasible. Outcome N N

Our response Our approach to producing phase two consultation materials sought to achieve a balance between the amount of general and technical information provided. We aimed to provide information in a form accessible for all to understand, while still providing sufficient information to comment on the issues we highlighted eg effects arising from the construction and operational phases. We also produced A guide to phase two consultation which provided further information on what information was available on different topics to aid navigation of the documentation produced. At each exhibition, members of staff were also available to answer any questions attendees may have had on our proposals. Members of the public could also access support through a dedicated phone line. Our approach to producing material was that information should be made available to members of the community in an accessible form and detailed technical information be made available for technical consultees and is consistent with the guidance provided by the Department for Communities and Local Government (DCLG) in its guidance on pre-application consultation.

Our response (four out of five) for each section (maximum score = 40). Should the site not be able to achieve a score of 32, an explanation indicating that the highest possible score has been achieved will be required from the contractor. The standards which contractors will be expected to commit to will be kept under review. We consider that we have undertaken a thorough and comprehensive consultation exercise. As part of this, we carefully considered the information we made available at our phase two consultation to ensure that consultees had sufficient information to respond to the consultation. This included details of the layout of the site during each of the construction phases as provided in the Carnwath Road Riverside site information paper. Further details regarding the construction period can also be found in the PEIR (volume 13) and the draft CoCP. We are confident therefore that the information we have provided is sufficient. There is no significance attached to the ordering of the issues. The order was not intended to reflect the relative importance of the identified issues. We have considered both construction and operational issues. Information on key issues associated with the site once it is operational is set out in the Carnwath Road Riverside site information paper. Further information relating to likely significant effects both during construction and operational can be found in the PEIR (volume 13). The measures proposed to address likely significant effects are being developed further and considered as part of the environmental impact assessment.

Our response Statement that will be submitted with our DCO application. An integral part of the pre-application process is the legal requirement that we consult with the communities and stakeholders in the vicinity of the tunnel route and the sites we intend to use in constructing and operating the project and that we take account of all the comments received in response to consultation. We also need to comply with advice issued by the Planning Inspectorate and guidance the Secretary of State in respect of the pre-application consultation requirements. The process is intended to be open and transparent and to ensure that project promoters give careful consideration to consultation responses and where necessary adjust their proposals accordingly. We are committed to this approach. At phase one consultation, we consulted on need to reduce the amount of sewage entering the River Thames; implementing a storage and transfer tunnel as a solution to address CSO discharges; the route of the tunnel; our preferred construction sites; and sought views on our initial design proposals for the sites. Consistent with the legal requirement, the project we are consulting on at phase two consultation takes account of the responses we received from phase one consultation and further engineering design refinements identified by the project team. The Changes project information paper, which summarises the principal changes emerging from phase one consultation, shows that we are listening to the feedback we receive on our proposals and where possible are amending our proposals to reflect the concerns being raised. Further details can be found in the Phase two scheme development report. This Report on phase two consultation sets out our view on how we intend to respond to the feedback received during this phase of consultation.

Objections, issues and concerns - Thames Water is not addressing construction impacts; it is just claiming that they don't exist - the assumptions underpinning the identification of issues are wrong - compromise would be less radical - there has been an 'agenda' from the start - there has been no attempt to measure or consult on an acceptable level of impact of various issues for local residents - consultation should allow the possibility of reversing the decision.

Our response low value site would not result in a site becoming our preferred site, if there were significant planning, environmental or community concerns associated with its use. In determining our preferred site, we made a balanced judgement, taking planning, environment, engineering, property and community considerations into account. We have sought to avoid or eliminate likely significant effects wherever possible by developing robust technical solutions to potential issues such as odour and through our proposals for the permanent site design and layout. We are also developing a CoCP which will set out how we will manage our construction sites to minimise disruption to nearby communities. The PEIR (volume 13), which was available for review and comment at phase two consultation, sets out the assessment methodology and assumptions on which the environmental impact assessment and identification of key issues is based. These assumptions and methodologies reflect industry best practice, and have been subject to extensive technical engagement as part of the environmental impact assessment scoping process. We are undertaking an environmental impact assessment, which will include a comprehensive assessment of likely significant effects arising from the proposals. The findings of the assessment, together with any recommendations for mitigation, will be available as a part of the Environmental statement that will be submitted with our DCO application. The feedback from phase two consultation has been subjected to careful analysis as presented in this report, which (in line with legislation and guidance) makes clear where we have made or are considering changes, ; where we are examining mitigation in response to the feedback; and where we are not making changes and the reasons for this.

As part of our PEIR (volume 13, section 4) we assessed the N air quality, traffic and residential amenity of the proposed development, based on a methodology that was discussed N and agreed with LBHF. The PEIR (volume 13, section 4) which covered air quality and odour topics includes the dust mitigation measures that are set out in the draft CoCP. While we acknowledge that this is a preliminary assessment, we believe that sufficient information was available for the N purposes of our phase two consultation. We are undertaking an environmental impact assessment, which will include a comprehensive assessment of the likely significant effects arising from the proposals. The findings of the assessment, together with any recommendations for mitigation, will be available as a part of the Environmental statement that will be submitted with our DCO application. Our Managing construction project information paper and draft CoCP set out how dust control measures and dust monitoring equipment would be put in place to minimise likely significant effects of dust from construction activities. Our draft CoCP confirms that an Air management plan will be prepared and implemented for each site to control dust emissions, with proposed techniques in line with best practice guidelines. Our preliminary assessment of air quality effects, as reported in our PEIR (volume 13, section 4), considered the likely significant effects of dust arising from the construction site. The report concluded that the effects of dust arising from construction would be reduced by the implementation of measures to be contained in the CoCP. Further assessment will be undertaken as part of our on-going environmental impact assessment work and this will be reported in the Environmental statement to be submitted with our DCO application.

Our response Health impact assessment for submission with the application. The Health impact assessment will assess the full range of potential health and well-being effects of the project on identified vulnerable groups. We have set out measures in our draft CoCP that will be adopted to limit vehicle and plant emissions, including using low emission vehicles, turning off engines when not needed, and minimising vehicle movements around the site. Our preliminary assessment, which is outlined in our PEIR (volume 13, section 4), sets out that with these measures in place we do not expect any significant local air quality effects arising from vehicle and plant emissions at this construction site. We are preparing a full assessment for submission within the Environmental statement as part of our DCO application this will include dispersion modelling. Dispersion modelling will assess the likely significant impacts of the construction phase at all proposed sites for the relevant short and long-term NO2 and PM10 air quality objectives. As a result of comments received during our phase two consultation we are considering the opportunities for further use of the river to transport materials during construction, which would reduce the number of lorries on local roads. Our preliminary assessment of air quality effects, as reported in our PEIR (volume 13, section 4), did not identify any likely significant effects near this site at residential properties or at the other identified sensitive receptors. These included commercial/leisure uses and Thomas's Fulham School. Eel Brook Common is a considerable distance from the site and has therefore not formed part of these site assessments. Further assessment of nearby properties will be undertaken as part of our on-going environmental impact assessment work and this will be reported in the Environmental statement to be submitted with our DCO application. Our draft CoCP confirms that an Air management plan will be prepared and implemented for each site, with proposed techniques in line with best practice guidelines. While not a formal requirement we are also preparing a Health impact assessment for submission with the application. The Health impact assessment will assess the potential likely significant health and well-being effects of the project on identified vulnerable groups.

Our response sufficient information to respond to the consultation. This included our PEIR (volume 13, section 4) which sets out initial assessment of likely significant effects on air quality from construction site activities including construction traffic, temporary closure of road lanes, emissions from barges and construction and construction-generated dust. The proposals set out in our draft CoCP are included in the assessment. Odour is not addressed as there are not expected to be any construction effects. It is not expected that sewage odours would be emitted since there is no sewer interception at this location. Further assessment will be undertaken as part of our ongoing environmental impact assessment work and this will be reported in the Environmental statement to be submitted with our DCO application. If significant effects are identified appropriate mitigation would be proposed. Our DCO application will also include a CoCP that will set out measures that must be implemented by our contractor to address the potential effect son air quality during construction. Our draft CoCP confirms that an Air management plan would be prepared and implemented for each site, with proposed techniques in line with best practice guidelines. We are confident therefore that the information we have provided is sufficient. We have completed a preliminary environmental assessment of the effects of the proposed development, which is set out in our PEIR (volume 13, section 4) which considers the likely significant effects of our construction in respect of air quality, dust, odour, noise and vibration, which singularly or collectively might be classed as 'pollution'. This did not identify any likely significant effects at residential or other sensitive receptors (such as schools and school children) near this site. A full assessment of potential 'pollution' will be presented in the Environmental statement that we will submit with our DCO application. We have also produced a draft CoCP which sets out measures for managing our works, including sections on noise, vibration, and air quality as well as details of the various regulatory regimes and guidance with which we would need to comply, such as the Control of Pollution Act 1974, the Environmental Protection Act 1990, the Health and Safety at Work Act 1974, the Mayor of London's Ambient Noise Strategy 2004 and The Control of Dust and Emissions from Construction and Demolition - Best Practice Guidance 2008, as well as various British Standards. Our compliance with the regulatory regime applicable will be monitored by LBHF.

If a Development Consent Order (DCO) is granted we would anticipate a series of requirements (similar to planning conditions) that would control the development. We expect that the requirements would secure the provision of the mitigation measures set out in the Environmental Statement that will be submitted with the application. In addition we would ensure compliance with the CoCP through the construction contract, which will require our contractor to adopt appropriate measures to avoid creating statutory nuisances where necessary.

Details relating to the site specific construction programme for this site are set out in the Carnwath Road Riverside site information paper, which indicates that construction works would last for a period of approximately six years. The programming of works at all sites will be configured to minimise the duration of works and associated disruption to the local area where possible.

As detailed in our site information paper, we plan to carry out site set up, shaft construction, construction of other structures and site completion within standard working hours, which are 8am-6pm weekdays, and 8am-1pm Saturdays. The shaft construction may require occasional extended standard working hours for reasons such as undertaking large concrete pours, delivering abnormal, large and heavy loads at times when there is reduced traffic. Weekend working hours additional to the standard working hours would be agreed with LBHF and we would notify the local residents beforehand. This site has been selected as a main tunnel drive site, which means that we will need to undertake continuous tunnelling in order to excavate and build the tunnel. Tunnelling needs to be carried out continuously to minimise settlement. It would also take considerably longer if we did not tunnel continuously. During continuous working hours, we will construct an acoustic building over the top of the shaft that will reduce the impact of noise and dust on the area. The movement of HGVs to and from the site would be limited in order to minimise likely significant environmental effects. For example, in residential areas, HGV movements may be limited to daytime to minimise noise at night.

Our response shaft-sinking. The definition of these hours, and the activities that take place during them are explained further in our draft CoCP. The CoCP defines the maintenance period for standard weekend hours as 1pm to 5pm on Saturday and 10am to 4pm on Sunday. The activities allowed in this period are limited, with no significant noise and vibration allowed. Maintenance activities will be limited and include general mechanical maintenance to construction machinery such as excavators plant such as compressors, grouting equipment, and dewatering equipment such as pumps. Where possible, maintenance works on Sundays would be avoided. We will have to undertake continuous 24-hour working during the tunnelling and secondary lining phase of the work, but we will limit noise as much as possible at night and will not be moving HGVs in or out of the site. Generally there is not a seasonal impact on the timescale of works but it is likely that an extent of dredging will be required to enable the use of the River Thames during construction. This may be restricted seasonally to avoid impacts on aquatic ecology.

Our response cement works, a petroleum depot and an asphalt works. We also identified a timber yard, a builders merchant and potential contamination of the shallow groundwater offsite. In order to understand the potential of any contaminants to affect human health during construction, we developed a source-pathway-receptor conceptual model for the site. The source-pathway-receptor model allows us to identify how, if at all, potential contamination could reach a receptor (in this case local residents or on-site workers). The pathways by which the potential below ground contamination could be mobilised during construction are: a. human uptake through: ingestion of exposed contaminated soils during construction or inhalation of soil/dust, volatilised compounds or ground gas via migration through permeable strata and conduits b. dermal contact with exposed soils during construction. Although the historic use of the site suggests that it is likely to be contaminated, this will be confirmed through detailed site investigation before construction. Even without the details of the exact contamination on the site we have set out how we would address any contamination issues through working practices to avoid the pathways described above from operating. These measures are set out in the draft CoCP which was included as part of the phase two consultation materials. The draft CoCP sets out a series of objectives and measures to be applied throughout the construction period in order to: a) set out the standards and procedures for managing and mitigating the impact of site activities during the construction of the Thames Tunnel project b) maintain satisfactory levels of environmental protection c) limit disturbance from construction activities and to assure all stakeholders that all construction impacts will be managed appropriately. The land quality (9), the air quality (7), water resources (8) and waste management and resource use (10) sections of the draft CoCP outline the legislation, policy and measures to which the contractor undertaking the work would be required to work. Application of the approaches and measures outlined in the draft CoCP will ensure that contamination is not a risk to human health during construction, either to those undertaking the work or to local residents. Section 4 of the draft CoCP outlines general site operations, including the avoidance and response to pollution incidents.

Our response Our Environmental statement, which will be submitted as a part of our DCO application, will assess the measures set out in our CoCP. Our contractor will be required to comply with those measures. Through the application of the measures in the CoCP the assessment in the PEIR (volume 13, section 8) determined that land quality effects on construction workers and off-site receptors would not be significant. We have made allowance in our project cost estimate for dealing with any contamination that is found in the ground. Ground remediation would be carried out in a safe controlled way, and would only be required for the volume of material required to be excavated for the shaft and other shallow structures, and not the whole site.

Our preliminary assessment of the effects on wildlife N associated with the construction of the tunnel are set out in our PEIR (volume 13, section 6), which sets out the likely N significant effects on notable species including bats and N birds and their habitats. The project has been designed to minimise effects on wildlife and habitats where possible. Where effects have been identified, mitigation has been built into the design. The likely significant effects will be assessed and reported in the Environmental statement that will be submitted as part of the DCO application. The CoCP that will be submitted with the application will ensure that works are undertaken in compliance with applicable legislation, and with relevant nature conservation policies and guidance, including the Mayor of Londons Biodiversity strategy and local biodiversity action plans. Where species are protected by specific legislation, we would follow approved guidance, propose appropriate mitigation and obtain any necessary licences or consents. We consider that we have undertaken a thorough and comprehensive consultation exercise. As part of this, we carefully considered the information we made available at our phase two consultation to ensure that consultees had sufficient information to respond to the consultation. This included our PEIR (volume 13, section 6) which sets out our initial assessment of likely significant effects on terrestrial ecology from construction site activities comprising clearance activities commencing in the first year of construction, piling, movements of construction workers and machinery that would cause noise, vibration and lighting, works within the foreshore and continuous 24-hour working. The proposals set out in our draft CoCP are included in the assessment. An assessment of the likely significant effects on the natural environment is being completed as a part of our N

Our response Pollution Act which sets out specific working methods and the measures to minimise noise and vibration. This will ensure that the noise levels are reasonable and best practical means are applied. The measures would be agreed with local authority environmental health officers. Additionally, we will implement best practice measures to minimise noise and vibration from plant and works including the selection of appropriate plant and equipment, siting of equipment, use of enclosures to provide acoustic screens At this site the shaft would also be enclosed by an acoustic shed for the period of 24-hour tunnelling. Full details of the measures that will be adopted for the construction will be set out in the CoCP submitted with our DCO application. At this site we will also use barges to transport materials, which will reduce noise associated with transportation of materials by road. Our PEIR (volume 13, section 9) sets out our preliminary qualitative assessment of noise and vibration from construction site activities including barge movements, noise from construction traffic on roads outside the site. and noise and vibration from operation of the site. The proposals set out in our draft CoCP are included in the assessment. The PEIR assessment was undertaken using used Defra's London noise maps. It concluded that noise from barges would be limited and would mainly consist of engine noise as the barge approaches or departs the site which would have a limited effect as it is assumed that engines would be switched off once moored. For road traffic, given the volumes of existing traffic on roads in the area the effect is likely to be low. The noise impact associated with HGV traffic is also set out in the PEIR (volume 13, section 9). Our Environmental statement, which will be submitted with our DCO application, will include an assessment of noise and vibration that will be completed in line with the methodology that is compliant with BS5228, BS6472 and BS7385and has been agreed with LBHF. We note that residential premises are located to the north, east and west of the proposed site. To the west there are three-storey residential premises (85 and 89 to 101 Carnwath Road). Block 89-101 does not have windows overlooking the site above the first floor. To the north over Carnwath Road is the Piper Building a six-storey mixed residential and commercial building with residential flats, from the third floor upwards.

Our response Outcome completed by the first year of construction, including the redevelopment of the Baltic Saw Mills site and Fulham Wharf. These developments are further away than receptors we have considered, and they have not therefore been included in the assessment. The residential properties and other sensitive receptors selected for the noise and vibration assessment are identified in our PEIR (volume 13, section 9) at Table 9.4.1. One non-residential noise sensitive receptor has been assessed, which is commercial space at 50 Carnwath Road, which is below part of the Piper Building. Refer to our response at paragraph 10.5.256 in respect of vibration effects. We are preparing a Health impact assessment to assess any likely significant effects on health which may arise from noise associated with the proposed development and this will be submitted as part of our DCO application. Our methodology for the assessment of likely significant noise and vibration effects, which has been agreed with LBHF, takes into consideration any relevant developments in the local area so we can ensure that the cumulative effects of our proposals can be properly assessed. We also note that assessment of cumulative effects is a requirement of the Infrastructure Planning (Environmental Impact Assessment) Regulations 2009. Our PEIR (volume 13, section 9) sets out the details of any relevant strategic developments that have been taken into consideration in our preliminary assessment. At this stage we concluded that although a number of new developments are likely to be partially completed by the first year of construction, including the redevelopment of the Baltic Saw Mills site and Fulham Wharf, these developments are further away than receptors we have considered, and therefore they have not been included in the assessment. We will continue to monitor proposed development in the local area and any relevant cumulative effects would be reported in our Environmental statement that will be submitted as part of our DCO application. Carnwath Road Riverside is proposed as a main drive site where there will be continuous tunnelling, although a proportion of our works would be undertaken in standard working hours as detailed in our site information paper. A preliminary assessment has been carried out that identifies that there are likely to be significant adverse noise and vibration effects during the construction phase at this site. Our contractor will be required to implement noise and vibration control measures at the site, in line with the N

Our contractor will be required to gain prior approval to the construction work from LBHF through a Section 61 application under the Control of Pollution Act that sets out specific working methods and the measures to minimise noise and vibration as well as any appropriate monitoring measures. The measures would be agreed with local authority environmental health officers. Additionally, we will implement measures to minimise noise and vibration from plant and works including the selection of appropriate plant and equipment, the siting of equipment, and the use of enclosures to provide acoustic screens. At this site the shaft and gantry crane would also be enclosed. Details of the measures that will be adopted for the construction will be set out in the CoCP to be submitted with our DCO application.

Outcome

10.5.154 Duration of construction and effects of associated noise and vibration.

At this site we anticipate that construction will last for six N years, as detailed in our site information paper. During the construction period there will be varying levels of noise and vibration associated with the different activities on site. As detailed in the PEIR (volume 13, section 9) at this site most stages of work have been assessed as having significant effects at eight receptors around the site. This assessment is based on a worst case assessment where the two noisiest activities in any stage happen concurrently and over the entire duration of the stage. This is a conservative approach and a full assessment of the likely significant effects will be set out in the Environmental Statement that will be submitted with our DCO application and this will incorporate appropriate mitigation measures where significant effects are identified. We anticipate monitoring noise and vibration where there are sensitive receptors. The requirements for monitoring will be agreed with local authority environmental health officers as part of our section 61 applications. We do not expect the monitoring equipment to have any effect on occupiers or users of adjacent or nearby sites. N

Our response BS7445 and has been agreed with LBHF. It is a robust approach to assessing likely significant noise effects associated with development. Our Environmental statement, which will be submitted with our DCO application, will include a full assessment of noise and vibration that will be completed in line with the methodology that is compliant with BS5228, BS6472 and BS7385 and has been agreed with LBHF. If significant noise and/or vibration effects are identified at a site, we will set out appropriate mitigation measures to provide appropriate attenuation. At this site we propose a temporary structure to enclose the shaft and gantry crane area. The final design of the enclosure is yet to be determined. However, our preliminary noise assessment assumes that the noise insulation performance of the enclosure is based on typical cladding material for this type of structure with consideration for ventilation and other openings. Further details of the design of the enclosure will be set out in our DCO application and the details of that design would be assessed in our full Environmental statement. Our phase two consultation has provided the community with an opportunity to comment on our proposals including levels of impact. In particular, question 4 on the feedback form sought comments on whether we had identified the correct key construction issues and mitigation measures. We note that our approach to assessing the impacts of the project has been prepared in line with best practice and British Standards where appropriate (such as the noise and vibration assessment) . Our works would be completed in line with the measures set out in our CoCP. We are discussing power requirements with utility providers and do not believe that power cuts or shortages area likely to be an issue. In the event that any loss was incurred as a consequence of our works, we have published A guide to the Thames Tunnel compensation programme which sets out details of compensation that would be available for damage or loss caused by our works. We have completed a preliminary assessment of likely significant effects of noise on the river and our findings are that noise from barges would be limited and would mainly consist of engine noise as the barge approaches or departs the site which would have a limited effect as it is assumed that engines would be switched off once moored, as set out in the PEIR (volume 13, section 9). Further details of likely significant noise effects on the river will be set out in the Environmental statement that will be submitted with our

Specific measures such as acoustic suppression systems, operation of equipment in the mode that minimises noise and shutting down equipment when not in use are also identified in our CoCP. Our contractor would be required to comply with the requirements of the CoCP. The CoCP also states that our contractor would be required to apply for section 61 consents (s.61) under the Control of Pollution Act 1974. These would set out specific working methods and the measures to minimise noise and vibration as well as any appropriate monitoring measures to be agreed with local authority environmental health officers. If a DCO is granted we would anticipate a series of requirements (similar to planning conditions) that would control the development. We expect that the requirements would secure the provision of the mitigation measures set out in the Environmental Statement that will be submitted with the application and would stipulate that the development must be carried out in accordance with the agreed CoCP. We note that we are currently considering the opportunity to increase use of the river to transport materials. An effect of increased use of the river would be a reduction in the number of lorries required during construction.

Specific measures such as acoustic suppression systems, operation of equipment in the mode that minimises noise and shutting down equipment when not in use are also identified in our CoCP. As set out in our Carnwath Road Riverside site information paper, the contractor would be required to implement noise and vibration control measures at the site, in line with the requirements of the CoCP. The contractor would also be required to gain prior approval to the construction work from LBHF through a Section 61 application under the Control of Pollution Act which sets out specific working methods and the measures to minimise noise and vibration. This will ensure that the noise levels are reasonable and best practical means are applied. The measures would be agreed with local authority environmental health officers. Additionally, we will implement best practice measures to minimise noise and vibration from plant and works including the selection of appropriate plant and equipment, siting of equipment, use of enclosures to provide acoustic screens At this site the shaft would also be enclosed by an acoustic shed for the period of 24-hour tunnelling. Full details of the measures that will be adopted for the construction will be set out in the CoCP submitted with our DCO application. At this site we will also use barges to transport materials, which will reduce noise associated with transportation of materials by road. Our PEIR (volume 13, section 9) sets out our preliminary qualitative assessment of noise and vibration from construction site activities including barge movements, noise from construction traffic on roads outside the site. and noise and vibration from operation of the site. The proposals set out in our draft CoCP are included in the assessment. The PEIR assessment was undertaken using used Defra's London noise maps. It concluded that noise from barges would be limited and would mainly consist of engine noise as the barge approaches or departs the site which would have a limited effect as it is assumed that engines would be switched off once moored.

Our proposals for the site will not compromise Hurlingham Wharf's safeguarded status with the location of our permanent works on Whiffin Wharf. The wharf offers the opportunity to use the river to transport materials from the site during construction, which is consistent with GLA policy. While the use of this site during construction of the tunnel will prevent it from being available for redevelopment in the short term, the permanent layout and design of the site minimises the amount of land that is needed permanently, allowing as much of the site as possible to be developed for its designated use.

10.5.198 Other planning and development issues included: - the only reason Thames Water is proposing to locate the project at this site is because they are legally bound to do so by the London Plan which prevents them from using a greenfield site if a viable alternative viable exists; this must be ruled out - characterisation of the site as a brownfield site that is in need of regeneration is misleading; do not see how a higher resale land value is a factor.

8537, 8681, 8878, 9303

Site selection has involved a multidisciplinary approach and N has considered community (including socio-economic) and environmental factors alongside planning (including policies on sustainable development), engineering and property considerations. Whether a site is brownfield or greenfield is one of many considerations taken into account as part of the site selection process when determining whether or not a site is suitable. Please also refer to our response at paragraph 10.3.29 above. Cost was also one of the considerations that inform site N assessments, but it is not an overriding factor that outweighs all other engineering, planning, environmental, community, property and wider economic considerations. High acquisition costs alone would not outweigh positive considerations such as use of brownfield land, conformity with planning policy, and ability to construct/operate the proposed works on the site. Equally, a low value site would not result in a site becoming our preferred site, if there were significant planning, environmental or community concerns associated with its use. In determining our preferred site, we made a balanced judgement taking planning, environment, engineering, property and community considerations into account.

A full assessment of the likely significant effects of the works on the local economy and businesses would be set out in the Environmental statement that we will submit with our DCO application. We are aware of the regeneration proposals set out in the draft South Fulham Riverside SPD and are developing our proposals to complement the development aspirations for the area. We acknowledge that our works will mean that delivery of the regeneration proposals will be delayed until our works are complete, but we believe that the wider benefits that will arise from the improvements to the River Thames will have a significant positive effect on the local area and its image. Landowners may have a statutory entitlement to claim compensation for the diminution on the value of their property due to the construction of the tunnel. In addition to the statutory process we have published an Exceptional hardship procedure which sets out how we will assess claims from householders who contend that they are suffering exceptional hardship as a result of being unable to sell their property because it is potentially impacted by the currently published Thames Tunnel project proposals. We have also published A guide to the Thames Tunnel compensation programme which sets out details of compensation that would be available arising from damage or loss during construction, for required protection measures, and for compulsory purchase. As set out in our draft CoCP (section 4.7) site security is an important issue to us and we would ensure that all sites are secure and staffed for security on a 24-hour basis; would have limited entry points and a boundary that minimises opportunities for unauthorised entry. We would also consult with local crime prevention officers to agree security proposals for each site and liaise regularly to review security effectiveness and responses to any incidents. The design of our site boundary would also ensure that there is adequate lighting (CoCP, section 4.6) in order to provide a safe route for passing members of the public and we would take precautions to avoid shadows cast by our site hoarding on surrounding footpaths and roads to limit the potential for muggings. Where agreed with LBHF, we would also have remote CCTV monitoring.

We consider that we have undertaken a thorough and comprehensive consultation exercise. We carefully considered the information we made available at our phase two consultation to ensure that consultees had sufficient information to respond to the consultation. Details of our proposals were set out in our site information paper and a preliminary assessment of the likely significant socioeconomic effects was set out in our PEIR (volume 13, section 10). We are confident therefore that the information we have provided is sufficient. The likely significant effect of the works on local schools would be set out in our Environmental statement, which will be submitted as part of our DCO application. Where likely significant effects are identified we would put in place appropriate mitigation measures to address those effects and we would discuss our proposed approach with LBHF and, where appropriate, with individual schools.

We have set out a range of measures that will mitigate the likely significant effects of the construction at this site. In particular our draft CoCP identifies that our contractor will be required to implement a range of measures at the site during construction, including best practice measures to minimise noise and vibration from plant and works including the selection of appropriate plant and equipment, the siting of equipment and the use of hoardings to provide acoustic screens. Additionally, our PEIR assessments take into account the mitigation measures set out in the CoCP and therefore assume that the mitigation is implemented. We are undertaking an environmental impact assessment, which will include a comprehensive assessment of the likely significant effects arising from the proposals. The findings of the assessment, together with any recommendations for mitigation, will be available as a part of the Environmental statement that will be submitted with our DCO application.

The preliminary assessment identifies that there is likely to be a significant effect arising from vibration associated with our works at 85 and 89-101 Carnwath Road, but that at all other assessed properties effects would not be significant. We will undertake an assessment of the impact of our works on the stability of the river wall and flood defences and where necessary we will provide strengthening to ensure that the walls integrity is maintained. The assessment will be undertaken to industry best practice guidelines and to the approval of the Environment Agency and other relevant stakeholders and would be reported in the Environmental statement that is submitted with our DCO application. Our Settlement project information paper provides information on our approach to controlling and limiting the ground movement, which can cause settlement, associated with construction of the tunnel. It is acknowledged that construction of the tunnel will cause some small movements in the ground, the level of which will depend on a range of factors including size and depth of construction works as well as existing ground conditions. The use of modern tunnelling methods and the depth of our tunnels, which are generally much deeper than most other tunnels in London, minimises the likelihood of any potential ground movement.

Our response We are assessing the potential likely significant effects of ground movement in advance of the works and, where necessary, will carry out protective measures. We will also monitor actual ground movement during and after the tunnelling to check that the ground is reacting as predicted. We will also carry out a defects survey on buildings located over, or close to, our tunnels and worksites where we consider this to be required. The method used for assessing settlement is similar to that used for the Channel Tunnel Rail Link, the Jubilee Line Extension, and Crossrail. In the unlikely event of damage occurring to property because of our construction works taking place nearby, disturbance compensation may be available as detailed in our A guide to the Thames Tunnel compensation programme. Any utilities close to or within our sites would be surveyed prior to and protected during construction. We do not consider the presence of the NG cable tunnel to be a factor that would preclude development at this site as we have located our shaft to the west of Carnwath Road Industrial Estate. Landowners may have a statutory entitlement to claim compensation for the diminution on the value of their property due to the construction of the tunnel. We have also published A guide to the Thames Tunnel compensation programme which sets out details of compensation that would be available arising from damage or loss during construction, for required protection measures, and for compulsory purchase.

The PEIR was available as part of our phase two consultation. We acknowledge that this is a preliminary assessment; we are preparing a full Transport assessment for submission as part of our DCO application.

Outcome

10.5.306 Disruption to the use of the Thames Path caused by construction works or diversion. 10.5.307 Concerned by diversion of Thames Path. 10.5.308 Effect of disruption, diversion or closure of pedestrian or cycle route.

At this site the existing Thames Path runs partially along N Carnwath Road as the riverside Whiffin and Hurlingham Wharf sites are currently inaccessible to the public. During N the construction phase it would be necessary to make a further temporary diversion to the Thames Path along N Carnwath Road, as illustrated in the Carnwath Road Riverside site information paper. This route has been selected because it would result in minimal diversion and is considered to be the best option for the temporary diversion. Footpath routes would be agreed with LBHF and TfL. It would provide a safe diversion of the Thames Path during construction. Cyclists will be able to continue using Carnwath Road as a cycling route during construction activities. Measures to ensure the safe crossing facilities for pedestrians and cyclists at our site entrances during the construction phase are outlined within our draft CoCP that was published at phase two consultation. Once the works are complete, the Thames Path will be reinstated along Carnwath Road and an additional length of footpath is proposed along Whiffin Wharf. It should be noted that Hurlingham Wharf is a safeguarded wharf which means that we cannot do anything that would prejudice its future use as an operational wharf. We are therefore unable to propose that the Thames Path is extended in front of Hurlingham Wharf. At this site we propose to use barges to transport the C majority of excavated materials from the shaft and tunnel. This is expected to reduce the number of lorry visits to/from this site by approximately 60 per cent. We are currently considering options to increase the use of barges at this site for the movement of materials during construction. An increase in the use of the river for transportation would result in a reduction in the number of lorry movements. Road access to this site is proposed via Carnwath Road which would link to the major road network to the north via Wandsworth Bridge Road and New Kings Road and to the south via Wandsworth Bridge Road, as illustrated in the Carnwath Road Riverside site information paper. It is noted that at the peak of construction at this site, an average of 33 lorries would visit (travelling to and from) the site each day, as indicated in the PEIR (volume 13, section 12). In the

Our response context of existing traffic in the local area, the expected construction traffic is not considered to be significant and is not likely to result in congestion on the Transport for London Route Network. We are reviewing the proposed routes that construction traffic would use as part of our transport assessment. If the transport assessment identifies any potential likely significant effects arising from congestion we will develop mitigation measures to minimise the effects of any disruption. We are also developing a CoCP (a draft was provided as part of our phase two consultation), which will include requirements for a Traffic management plan to ensure that construction traffic is carefully controlled to minimise any likely significant effects on the road network including access to the local area, as well as setting out construction traffic routes, site access/egress points, signage and monitoring procedures. As part of our PEIR (volume13 , section 12) we assessed the likely significant construction transport effects of the proposed development on pedestrian and cycle routes; bus and other public transport routes; patronage; parking; and highway layout, operation and capacity. As part of the assessment we have considered the likely significant effects of lorry and (where applicable) barge transport including likely significant effects of construction traffic on Carnwath Road and Wandsworth Bridge Road based on a methodology that has been discussed and agreed with LBHF and TfL. The PEIR was available as part of our phase two consultation. We acknowledge that this is a preliminary assessment; we are preparing a full Transport assessment for submission with our DCO application. The Transport assessment will consider the cumulative effects of our works with other strategic developments in the local area.

Our response We believe that the proposed access route as set out in the Carnwath Road Riverside site information paper is suitable for construction traffic, subject to some minor modifications to the junction of Carnwath Road and Wandsworth Bridge Road. The site has good access to the TfL road network, particularly to the south of Wandsworth Bridge. We do not envisage that construction traffic will cause any damage to local roads as, where possible, we will use the major road network which is designed and built to handle this type of traffic. We would monitor any effects on other roads used by our construction vehicles to ensure that any damage that is directly attributable to the project is quickly repaired. Measures that may be required to restore any damage roads to their existing condition is set out in our draft CoCP that was published at phase two consultation. The site has good access to the major road network which is designed and built to handle this type of traffic. We have carefully considered the options for access to the site and believe that the proposed access is suitable, especially as similar types of vehicles already visit the existing industrial estate. If necessary we would remove the traffic calming measures on Carnwath Road during the construction works. At this site we also propose to use barges to transport the majority of excavated materials from the shaft and tunnel. This is expected to reduce the number of lorry visits to/from this site by approximately 60 per cent. Preliminary design has been undertaken for the range of vehicles that would use the access to ensure that the proposed project complies with all required design and safety standards. Our transport assessment will inform the nature of off-site junction improvements required before our work starts. Where these are necessary, such as improvements to the junction of Carnwath Road and Wandsworth Bridge Road, we would carry out these improvements as early works in our construction programme. Based on our current proposals for this site, we do not believe that it would be necessary to relocate any bus stops. The likely significant effects of construction traffic on bus routes and patronage will be discussed with TfL and assessed by our Transport assessment which will be submitted with our DCO application. Some on-street car parking on Carnwath Road will be temporarily lost during construction. We are currently considering possible alternative locations for replacement on-street parking and will work closely with LBHF to review

There will be a requirement to ensure the proposals do not endanger safe school access. The transport assessment will also review data relating to recent accidents. However, it is inherently difficult to predict future accident rates with any certainty, particularly within an urban area, as they are influenced not only by the physical layout of the highway but also other factors such as the behaviour of all road users and prevailing weather conditions. The proposals will be subject to independent external review by TfL and the local highway authority to ensure proposed highway layouts and vehicle movement arrangements are as safe as possible.

Our response excavated material by river barge is the most cost-effective solution for this site.

Outcome

10.5.332 The site is not suitable to enable the river to be used to transport materials; can only happen in a small window of time twice a day when the tide is right. 10.5.333 Physical site constraints including tidal patterns will limit the potential to transport materials by barge, only usable at high tide.

7567, 8215

We believe that this site is suitable for transporting materials N by river. Part of the site, Hurlingham Wharf, is a safeguarded wharf and the proposed use is consistent with GLA policy in this regard. Tidal patterns have been taken into account in developing our strategy for moving materials by barge from this site. Based on the studies that have been completed to date, this matter is not considered to constrain the use of barges at this site. Our PEIR (volume 13, section 12), which was provided at phase two consultation, considers the likely significant effect of construction workers travelling to the site on local traffic volumes, parking and on the public transport network. This states that most staff will be required to travel to and from the site by public transport and concludes that this would not have a significant adverse effect. The Transport assessment to be submitted with our DCO application will further assess the likely significant effect of construction worker travel. Additionally, our draft CoCP, which was published as part of our phase two consultation, confirms that a Traffic management plan will be developed for this site that would ensure that construction traffic is carefully controlled to minimise any likely significant effects on the road network including access to the local area, as well as setting out construction traffic routes, site access/egress points, signage and monitoring procedures. The proposed working hours for the site are set out in the site information paper and draft CoCP and these working hours would also apply to traffic coming to and from the site. As part of our preliminary transport assessment we have considered the likely significant effects of lorry and where applicable barge transport within these working hours, based on a methodology that has been discussed and agreed with LBHF and TfL. As part of the development of our CoCP we will consider how we can take into account rush hours and school opening and closing times. We carefully considered the information we made available at our phase two consultation to ensure that consultees had sufficient information to respond to the consultation.

Our response transport some materials by road. At this site use of barges would remove approximately 44,000 lorries from the road during the construction. We are currently considering options to increase the use of the river for transportation of materials during construction.

Outcome C

Our proposals include transportation of 90 per cent of the excavated material from the shaft and tunnel by barge. As the site is not close to a railway line, this form of transport is not considered viable at this site. It is not currently part of our proposals to provide a permanent pier or new slipway on completion of our works. This is to ensure the operations of the safeguarded wharf are not affected by our proposals. Environmentally vehicles are not currently a mainstream technology. However, we recognise that the project is not expected to begin for several years and that is will take a number of years to complete. Therefore we will encourage our contractor to investigate the opportunities to utilise environmentally friendly vehicles during construction. Our use of the Hurlingham Wharf is consistent with its designation as a safeguarded wharf and our works will not prejudice its use as a wharf after construction is complete. Our transport assessment will inform the nature of off-site junction improvements required before our work starts. Where necessary, such as improvements to the junction of Carnwath Road and Wandsworth Bridge Road, we would carry out these improvements as early works in our construction programme. Our Environmental statement will assess the cumulative effects in combination with other strategic developments within the area, in line with the methodology that has been agreed. We are preparing a Transport assessment that will be submitted as a part of our DCO application. This will include a detailed analysis of potential access routes and an assessment of the likely significant effects of construction traffic on local roads, together with mitigation that is required to minimise disruption resulting from our site traffic. We will work closely with TfL, LBHF, local residents and other interested groups to minimise the likely significant effects of traffic movements to and from the site.

Our response the CoCP. Barge loading will be carefully controlled to avoid spilling material into the river. Whilst we do not anticipate any significant effects at this stage, the river bed will be monitored throughout the construction period and if it is found that the river bed level is changing, corrective action will be taken to ensure that the use of Broomhouse Pier and the Broomhouse Lane public drawdock are not adversely affected by the works. We are currently considering options to increase the use of the river for transportation of materials during construction. This could include constructing a jetty rather than a campshed at this site. However, this will be in discussions with the PLA and EA and will consider how to mitigate any potential additional effects upon the river bed.

Outcome N

10.5.364 Concerns that the pattern of river bed/sediment transport will change during construction. The jetty currently has a very low under keel clearance and this may be worsened due to the works. Removal of excavated material by barge is likely to result in deposition of additional materials into the river due to barge loading activities. The volume of this material may considerable given the duration of tunnelling works. There was concern that this additional material will raise bed levels either at Broomhouse Pier or the adjacent Broomhouse Lane public draw dock.

If, as part of the process of preparing our Environmental statement for submission with our DCO application, the need for additional mitigation is identified we will propose further measures. This may include scour protection measures including riprap if necessary. We would seek to limit the extent of these protective measures to minimise impacts upon the foreshore. We are carrying out fluvial and scour assessment of the temporary foreshore works to establish the likely significant effects of the development on the river, and will discuss the findings with the PLA and EA. Outcome N

10.5.366 Mitigation proposed to address the issues is inadequate/insufficient and placement of riprap or gabions should be avoided due to further encroachment on foreshore. 10.5.367 More information is needed on mitigation including monitoring proposed for any changes in the river flow and hence the potential for scour related to barge movements.

9253

10.5.368 Other water mitigation, including: reducing the causes of scour or strengthening the existing defences themselves. Where this cannot be done, justification needs to be provided and encroachment caused by these strengthening options needs to be mitigated and compensated for.

EA, 9253

Your comments are noted. The temporary works have been N designed in such a way as to minimise scour. Where significant scour is predicted, we will carry out preventative measures (such as placing riprap on the river bed), and in all locations the riverbed will be monitored and remedial works carried out if required. Riprap presents a change in habitat rather than a loss of habitat. Recommended water mitigation measures will be provided as part of our Environmental statement which will be submitted with the application.

Supportive and neutral comments diagonally - support the intention to create a wellarticulated building envelope that allows glimpses of the operations within from the street. The design enables the site to be used for other purposes once works associated with the Thames Tunnel project are complete. The size and/or height of the permanent buildings and structures is acceptable. Any work that is to be carried out should leave the site in the same/better condition when work is finished. Other qualified support: support finished proposals but not on the Carnwath Road Riverside site as it is highly residential. Elsewhere, the opportunity may arise where re-landscaping could blend it within the site after completion of works. Support for specific design feature: nature design.

Our response operational phase of the development. A full Transport assessment is being prepared for submission as part of our DCO application. As set out in our site information paper vehicles required for site maintenance would normally comprise of a small van every three to six months. Periodically (approximately every ten years) there would be a more detailed site inspection, which would require more vehicles, including two cranes. Given the infrequency of these inspections and the low number of vehicles involved there is not considered to be a traffic effect. Your comments are noted. Refer to paragraph 10.5.72 above for our response to feedback on the duration of our construction phase. Your comments are noted and we are considering how the permanent structures at this site might change from the proposals set out at phase two consultation. It should be noted that the structures associated with ventilation of the tunnel are informed by a number of functional requirements which means that there are physical limits as to how small we can make our structures to ensure they are fit for purpose. Prior to our phase two consultation we discussed our approach to design for this site with the Design Council CABE which identified in their written comments that the ventilation structures should be treated as a piece of engineering architecture to be celebrated and which supports the creation of a new riverside space and which can be located close to future development blocks (not related to the tunnel), as detailed in the Design development report provided at phase two consultation. Accordingly we have sought to make the visual appearance of the ventilation columns celebrate the nature of the Thames Tunnel project while meeting functional engineering requirements, in accordance with the design principles set out in the Design project information paper within our phase two consultation material. The Site selection background technical paper, which accompanies the Site selection methodology paper, specifies the site sizes for CSO and main tunnel site. We have used this criterion for selecting our preferred sites. Carnwath Road Riverside is therefore an appropriate size to accommodate our proposals. Your comments are noted. We have sought to locate the ventilation column so it is as far from homes as possible,

Outcome N

More concerned about the duration of the construction phase and associated disturbance and visual effects rather than the finished design. The permanent buildings and structures are too large/ tall. The ventilation column(s) are too high/big, why is this needed if there will be no smell?

Our response taking account of the functional requirements. We are currently considering the layout of our permanent facilities at this site.

Outcome C

The site is not fully occupied with limited plants and N ecological value. Our proposals would incorporate measures such as planting of trees and a biodiverse roof to encourage biodiversity at the site. Once our works are complete we do not anticipate any disruption to the use of the Thames Path, although as detailed in our site information paper it is acknowledged that there will be short period approximately every ten years when a diversion may be required to allow inspection and maintenance works. We would discuss the timing of the inspection/maintenance and any diversion with LBHF and ensure that appropriate signage is provided. We believe the final design of the site will not have a negative effect on local recreation and leisure. Our current proposal is to landscape the area around the shaft in order to create a positive aspect of potential and flexible public realm within this riverside location, providing an amenity to existing and future residents. Our permanent proposals seek to open up the site and to provide a landscaped area adjacent to the river to enhance the local area. We hope that this will be become an important and well-used area of public realm for residents, workers and tourists. Landowners may have a statutory entitlement to claim compensation for the diminution on the value of their property due to the operation of the project. N

Our PEIR (volume 13) provides a preliminary assessment of the likely significant effects of the proposals on a range of topics, including noise and vibration, air quality (including dust emissions), odour, and transport, based on a methodology that has been agreed with LBHF. A full assessment will be provided with the Environmental Statement that is submitted with our DCO application. N

Our response We are also preparing a Health impact assessment that will examine the likely significant effects of the proposed development on human mental and physical health and wellbeing and possible effects within the population. The findings of this study will inform the design for this site as well as mitigation measures to address any significant effects. Your comments are noted, we have included a number of measures in our proposals for this site to deliver sustainability measures, such as the incorporation of biodiverse roof. Your comments are noted and will be taken into consideration in developing our proposals for this site. Your comments are noted. We note that we have sought to make the visual appearance of the ventilation columns interesting while meeting functional requirements. The proposals seek to balance cost with a range of other factors, including operational requirements and delivering a scheme that will enhance and add to the local area. We do not consider that our proposals are too expensive or costly. We are developing our proposals for maintenance of the site and will discuss these with LBHF.

Outcome

10.6.55

Design proposals appear to be unsustainable/are not environmentally friendly. The scale of the permanent buildings and structures is out of keeping with existing buildings in the surrounding area. Design will have a negative effect on the character and setting of the riverside/river frontage, particularly the 50 foot high ventilation structure. Designs will be expensive/are too costly.

As detailed in our site information paper the area surrounded by the blue fence/sanded area is part of Whiffin Wharf which would be developed by others. The 'blank' area to the east is the remaining site of Hurlingham Wharf and Carnwath Road Industrial Estate. These sites would be developed by others. Illustrative plans were provided as a part of the Book of plans as part of the phase two consultation. The future development of the site by others will be determined by LBHF and planning policy for this site is currently being prepared. We will consider whether the campsheds could be left once the works are complete.

Our response this site, including reducing the scale of the buildings required and potentially removing the ventilation building from this site. Your comments are noted. We have sought to make the visual appearance of the ventilation columns interesting while meeting functional requirements. Our PEIR (volume 13, section 10) sets out a preliminary assessment of the likely significant socio-economic effects of the operational scheme, which concludes that there are not likely to be any significant adverse effects (that is major or moderate) in the operational phase that would require mitigation. A full Environmental Statement would consider the likely significant operational effects based on any new information and present this as a part of our DCO application. Your comments are noted. We have sought to make the visual appearance of the ventilation columns interesting while meeting functional requirements.

Outcome

10.6.61

Visual effect of ventilation columns and other permanent buildings and structures. Proximity of ventilation columns to sensitive receptors including schools.

Design measures to reduce the potential effects of the proposals are unsatisfactory/insufficient. Proposals do not create anything for the future (legacy) or bring any benefit to the local area.

We believe that our proposals for this site will deliver a N legacy for the local area through the provision of a new open space alongside the river. In our site information paper we aimed through a combination of photomontages and plans to illustrate how the completed scheme could look once complete. We need to develop our final proposals in response to the findings of the consultation, which means that the designs may change. If a Development Consent Order (DCO) is granted we would anticipate a series of requirements (similar to planning conditions) that would control the development. We expect that the requirements would secure the provision of the mitigation measures set out in the Environmental Statement that will be submitted with the application. Your comments are noted. N

Our response residents. This would make use of the permanent shaft hardstanding and provide an area of useable open space for the occupants of any new development on Whiffin Wharf and members of the public. We are currently considering the layout of the site including how the areas of open space within the operational site could be designed. New tree planting is proposed within the site boundary, rather than adjacent to Carnwath Road. The ventilation columns and other structures have been designed to meet functional and health and safety requirements and need to be the size identified to ensure that the tunnel can operate efficiently. We are currently reviewing our proposals for this site, including the location and height of the ventilation column The proposed odour control units will contain activated carbon filters. This is standard technology used worldwide and in the UK, for example the foul sewage pumping station for the Olympic Park in Stratford has just installed this type of odour control system. Refer to our response at paragraph 10.7.68 for details how redundancies have been built into our proposed project. The site is allocated for housing and employment uses within the wider South Fulham Riverside Regeneration Area in LBHF's adopted Core Strategy. While the use of this site during construction of the tunnel will prevent it from redevelopment in the short term, much of the site can be redeveloped in line with its allocation upon completion of our works.

Design should include improved children's playground facilities. Specific design amendments included: - the site between the existing housing and the western side of the shaft access will be left like an island and presumably would be of little worth as a future development site. Either the vent needs to be in the middle of the entire site proposed to be used, thereby leaving two decent future development sites either side of it, or to one side so as to maximize the area of a single future redevelopment site - the walls should be clad in brickwork - the building should be rotated 90 degrees to minimise the impact and open up the green areas to allow them to be seen from the road - why not consider what was done with the LU vent shaft at the front right side of Charing Cross Station which was a visual eyesore for several years but was then incorporated into the subsequent office development on that site and now cannot be seen - cut off temporary sheet piles at 1m below bed level, and remove all new concrete, to allow the foreshore to re-establish itself

This section sets out feedback comments received during the phase two consultation in relation to the management of operational effects at Carnwath Road Riverside. This includes the identification of site specific issues associated with the site once it is operational and proposals to address the effects of these issues. During the phase two consultation, respondents were asked whether the site information paper had identified the right key issues associated with Carnwath Road Riverside once the site is operational and the ways to address these issues (see questions 7a and 7b of the phase two consultation feedback form, provided in appendix M of the Main report on phase two consultation). The first part of question 7a and 7b asked respondents to select agree, disagree or dont know/unsure. Where respondents completed this part of the question, the results are set out in tables 10.7.1 and 10.7.2. Tables 10.7.3 to 10.7.34 detail the feedback comments received in relation to this site.

The proposals presented at phase two consultation reflect the issues raised by local residents during previous consultation activities. The purpose of phase two consultation was to further explore the issues and concerns of local residents to make sure that, where possible, the principal concerns of local residents are taken into account. This Report on phase two consultation sets out our view on how we intend to respond to the feedback received during this phase of consultation. Our DCO application for development consent must be accompanied by a Consultation report explaining how we have responded to public consultation including explanations of instances where no change to the project design is proposed in response to comments received through consultation. The process is intended to be open and transparent to ensure that project promoters give careful consideration to consultation responses and, where necessary, adjust their proposals accordingly. Our site selection process has had full regard to possible likely significant effects on the local area and community, and the environmental impact assessment process will undertake further assessment and recommend any necessary mitigation measures. In particular, the environment and community assessments undertaken as part of site selection had regard to the number and nature of sensitive receptors and possible impacts from traffic and in terms of noise, air quality, and visual impact. We also considered impacts on employment uses and possible conflict with planning policy seeking to protect local amenity.

Outcome

The measures set out in the Carnwath Road Riverside site N information paper are intended to provide a broad overview of how we intend to address potential issues associated with the site. Further information can be found in the PEIR (volume 13). Measures proposed to address likely significant effects are being further developed and considered as part of the environmental impact assessment. The findings of the assessment, together with any recommendations for mitigation, will be available as a part of the Environmental statement that will be submitted with our DCO application. As part of the site selection process (as detailed in our site selection methodology paper and supporting technical background paper) and scheme development, a number of factors have been taken into account, including planning, environmental, engineering, property and community considerations. Further details can be found in the Phase two scheme development report and Design development report. N

We have sought to address likely significant effects N occurring in both the construction and operational phases. The range and type of effect during each of these phases is likely to be different, and we have developed specific mitigation measures that will respond to the particular range of effects occurring at any particular site. Potential issues associated with the site during construction are set out in the PEIR (volume 13). We consider that we have undertaken a thorough and comprehensive consultation exercise. As part of this, we carefully considered the information we made available at our phase two consultation to ensure that consultees had sufficient information to respond to the consultation. Further information relating to likely significant operational effects can be found in the PEIR (volume 13). We are confident therefore that the information we have provided is sufficient. The feedback from phase two consultation has been the subject of careful analysis as presented in this report, which (in line with legislation and guidance) makes clear where we have made changes, such as the consideration of alternative sites as well as technical solutions; where we are examining mitigation in response to the feedback; and where we are not making changes and the reasons for this.

Our response the tunnel. We set out a preliminary assessment in the PEIR (volume 13). We are undertaking an environmental impact assessment of the project which will identify measures to address any significant adverse effects and these measures will be implemented by our contractor. An Environmental statement, which records the findings of the environmental impact assessment, will accompany our DCO application. We sought to achieve a balance between the amount of general and technical information provided. We aimed to provide information in a form accessible for all to understand, while still providing sufficient information to comment on the issues we highlighted eg effects arising from the construction and operational phases. We also produced A guide to phase two consultation which provided further information on what information was available on different topics to aid navigation of the documentation produced. At each exhibition, members of staff were also available to answer any questions attendees may have had on our proposals. Members of the public could also access support through a dedicated phone line.

Our response The key issues set out in the site information paper are intended to provide a broad overview of likely significant effects and key issues associated with the site once it is operational. It is not however an exhaustive list. Further potential issues associated with the site and measures to address these are set out in the PEIR (volume 13). We believe that the measures set out in the site information paper will address and/or reduce the likely significant effects satisfactorily. Measures proposed to address likely significant effects are being further developed and considered as part of the environmental impact assessment. We are undertaking an environmental impact assessment, which will include a comprehensive assessment of likely significant effects arising from the proposals. The findings of the assessment, together with any recommendations for mitigation, will be available as a part of the Environmental statement that will be submitted with our DCO application. We have sought to avoid or eliminate likely significant effects wherever possible by developing robust technical solutions to potential issues such as odour and through our proposals for the permanent site design and layout. If a Development Consent Order (DCO) is granted we would anticipate a series of requirements (similar to planning conditions) that would control the development. We expect that the requirements would secure the provision of the mitigation measures set out in the Environmental Statement that will be submitted with the application. We believe we have identified key issues. Once the tunnel is operational, we propose to undertake performance monitoring as well as regular inspection and maintenance visits which will allow us to identify any unforeseen effects and put in place suitable measures to manage them. We have sought to understand the concerns of residents through our consultation process. The proposals presented at phase two consultation reflect the issues raised by local residents during previous consultation activities for the project and our preliminary assessments at this site. The purpose of phase two consultation was to further explore the issues and concerns of local residents to make sure that, where possible, the principal concerns of local residents are taken into account.

A further quantitative assessment will be presented in the Environmental statement that is submitted with our DCO application. The assessment methodologies are based on best practice and have been agreed with LBHF. The ventilation facilities are designed to minimise the release of untreated air from the tunnel system and for 99.6 per cent of average year, air released from the tunnel will be treated and will not have any odours. This arrangement meets the Environment Agencys odour criteria. When the tunnel is empty, the ventilation system is operated so as to maintain a pressure lower than atmospheric pressure hence preventing air from leaving the tunnel. This is achieved by extracting air at specific active ventilation facilities which are currently proposed at our sites at Acton Storm Tanks, Carnwath Road Riverside, Greenwich and Abbey Mills pumping stations where the air is treated before being released through a high ventilation column. When the tunnel fills with sewage, the air path throughout the tunnel is gradually lost and air will be displaced by the rising sewage levels.

Our response Outcome is treated before being released. The technology which included carbon filtration has been used at the Olympic Park in Stratford, where it has been demonstrated to operate effectively to control emissions. We are confident that our proposed technology achieves the regulatory requirements. Our Air management plan sets out the ventilation emissions for a typical year at each site. At Carnwath Road Riverside untreated exhaust will be released for 34 hours over 14 events per year and the remaining 99.6 per cent of exhaust will be fully treated. Where the untreated exhaust is released (0.4 per cent of the time), the odour will still be within the strict limits set by the Environment Agency. We do not anticipate that there will be any dust arising from 10.7.54 the operation of the tunnel or from general inspection and maintenance activities at this site. 10.7.56 Our preliminary assessment of the likely significant effects of air pollution associated with operation of the tunnel is set out in our PEIR (volume 13, section 4). The PEIR concludes that when the tunnel is operational no significant effects are predicted in relation to air pollution. We do not anticipate any significant air pollution as we have developed an Air management plan to ensure the tunnel is operated in such a way to control odour. At this site we are proposing the use of a mechanical ventilation system that draws air through the tunnel with fans before cleaning the air using carbon filters that absorb possible odour before the air leaves the ventilation equipment. After treatment, air from the tunnel is discharged via a ventilation column, further mitigating any possible impacts on local air quality. We are also preparing a Health impact assessment for submission with the application. The health impact assessment will assess the likely significant effects of the project on the health of identified vulnerable groups. If significant effects are identified appropriate mitigation would be proposed. N N N N N

Our response Refer to our response at paragraph 10.3.29 above. Our preliminary assessment of the likely significant effects of odour associated with operation of the tunnel is set out in our PEIR (volume 13, section 4). The PEIR concludes that when the tunnel is operational no significant effects are predicted in relation to odour. We are undertaking an environmental impact assessment, which will include a comprehensive assessment of the likely significant effects of operation on air quality and odour. The findings of the assessment, together with any recommendations for mitigation, will be available as a part of the Environmental statement that will be submitted with our DCO application. If a DCO is granted we would anticipate a series of requirements (similar to planning conditions) that would control the development. We expect that the requirements would secure the provision of the mitigation measures set out in the Environmental Statement that will be submitted with the application. The proposed odour control units will contain activated carbon filters. This is standard technology used worldwide and in the UK. The technology has been used at the Olympic Park in Stratford, where it has been demonstrated to operate effectively to control emissions. We are confident that our proposed technology achieves the regulatory requirements. The ventilation facilities are arranged to minimise the release of untreated air from the tunnel system and for 99.6 per cent of average year, air released from the tunnel will be treated and will not have any odours. Odour is subjective and therefore the project is obliged to apply the Environment Agencys odour criterion which states that we should not exceed 1.5 odour units per cubic metre of air for 98 per cent of the time during the average year. We will achieve this criterion at all sites. It should be noted that 1.5 odour units per cubic metre is barely perceivable by most people and the average background odour in cities is between five to 60 odour units per cubic metre. When the tunnel is empty, the ventilation system is operated so as to maintain a pressure lower than atmospheric pressure hence preventing air from leaving the tunnel. This is achieved by extracting air at specific active ventilation facilities which are currently proposed at our sites at Acton Storm Tanks, Carnwath Road Riverside, Greenwich and

When the tunnel fills with sewage, the air path throughout the tunnel is gradually lost and air will be displaced by the rising sewage levels. This air will pass through mechanical filters where it is treated before being released. The tunnel ventilation system has a number of redundancies built in and works as a complete system so that in the unlikely event of a failure at one site the required through put of air can be maintained by increased ventilation elsewhere in the system. The systems will be monitored and replacements for elements such as the passive filters planned in advance of their end of their design life.

As detailed in our PEIR (volume 13, section 9) noise control measures would be included on all plant items as part of the design process to limit noise increases to within appropriate noise limits to avoid disturbance, in accordance with British Standards. We are undertaking an environmental impact assessment, which will include a comprehensive assessment of the likely significant effects arising from the proposals. The findings of the assessment, together with any recommendations for mitigation, will be available as a part of the Environmental statement that will be submitted with our DCO application. If a Development Consent Order (DCO) is granted we would anticipate a series of requirements (similar to planning conditions) that would control the development. We expect that the requirements would secure the provision of the mitigation measures set out in the Environmental Statement that will be submitted with the application.

The wharf offers the opportunity to use the river to transport materials from the site during construction, which is consistent with GLA policy. The site is allocated for housing and employment uses within the wider South Fulham Riverside Regeneration Area in LBHF's adopted Core Strategy. While the use of this site during construction of the tunnel will prevent it from redevelopment in the short term, much of the site can be redeveloped in line with its allocation upon completion of our works. We have designed the permanent layout and design of the site to minimise the amount of land that is needed permanently, allowing as much of the site as possible to be redeveloped. Our proposals for the permanent layout and design of the site will also bring long-term benefits to the local area, including the creation of a new public open space with tree planting and landscaping, possible road junction improvements and an extension to the Thames Path pedestrian walkway.

Our response Statutory procedures are in place to enable qualifying landowners to serve notice requiring compulsory purchase of land that is blighted. Any qualifying claims for statutory blight can be made after the DCO application has been submitted. In addition to the statutory procedures, we published our exceptional hardship procedure at phase two consultation. This procedure goes beyond the legal requirements and enables property owners meeting certain criteria to apply to us to purchase their property voluntarily. Further information is available on our website. One of the key development constraints in the local area identified in the draft South Fulham Riverside SPD is the capacity of the existing highways. An objective of the SPD is therefore to improve local road infrastructure to accommodate the increase in residential and other uses, which will ease congestion at junctions and improve connectivity to transport nodes. Improved local road infrastructure delivered as part of our proposals will help to contribute towards the achievement of this objective while removing some of the highway constraints in the local area that may currently be preventing potential development interests from coming forward.

Outcome N

10.7.117 Proposals will lead to planning blight in an area with the potential to attract great business.

The draft South Fulham Regeneration SPD identifies the C need to improve both physical and visual permeability in the local area by promoting access through new developments and, where possible, introducing new access to the riverside. Our proposals for the permanent layout and design of the site reflect and contribute towards both of these objectives. We also have designed the permanent layout and design of the site to minimise the amount of land that is needed permanently, allowing as much of the site as possible to be redeveloped and regenerated in line with the LBHFs planning policies and objectives.

Our response Given the infrequency of these inspections and the low number of vehicles involved there is not considered to be any effect.

The strengthening works proposed to Hurlingham Wharf are N essential to the future use of the existing safeguarded wharf and are consistent with GLA policy. As described in the Build project information paper, our tunnel will be built using a closed face TBM. This type of machine is very secure and well tested in the clay soils such as those under Carnwath Road Riverside. The front section of the tunnel is fully supported by the shell of the machine itself and the reinforced concrete tunnel lining is erected in the machine as it moves forward. At no point in the process is the ground left unsupported. Our tunnel will also be built to comply with all appropriate regulations and policies and best practice, such as the British Standards. The work of the contractor building the tunnel will be subject to review and observation by independent supervisors. With these measures in place, tunnel collapse is an extremely remote possibility.

Our response If a Development Consent Order (DCO) is granted we would anticipate a series of requirements (similar to planning conditions) that would control the development. We expect that the requirements would secure the provision of the mitigation measures set out in the Environmental Statement that will be submitted with the application. We believe that the development of our proposed site will not preclude the future development of the Thames Path in this area. Our plans presented at phase two consultation show that the Thames Path would be reinstated along Carnwath Road and an additional length of footpath is proposed along Whiffin Wharf. It should be noted that Hurlingham Wharf is a safeguarded wharf which means we cannot do anything that would prejudice its future use as an operational wharf. Your comments are noted and will be taken into consideration in developing our designs for this site. Our PEIR (volume 13, section 12) sets out a preliminary assessment of the likely significant transport effects of the operational phase of the development. A full Transport assessment is being prepared for submission as part of our DCO application. Details of the site maintenance activities were set out in our site information paper. The maintenance works require access to the plant and structures and therefore it is not likely to be feasible to access these from the river. It is not currently part of our proposals to provide a permanent pier or new slipway on completion of our works. This is to ensure the operations of the adjacent safeguarded wharf are not affected by our proposals. In developing our proposals for this site we have been mindful of the wharf's safeguarded status, and our permanent works would not preclude utilisation of the wharf for cargo handling.

Our PEIR (volume 13, section 15) sets out a preliminary N assessment of likely significant effects on flood risk (level one) in line with the requirements of PPS25 and considers flooding from the sea (and tidal sources), rivers, land and surface water runoff, and groundwater. As set out in our PEIR the site is in Flood zone 3a where there is a high probability of flood risk. Our modelling to date indicates that the operational scheme would not require compensatory flood storage in this location. However, as our designs develop we will review the likely significant operational effects on flood risk to determine any requirements for storage. A level two flood risk assessment will be presented in the Environmental statement as part of our DCO application and will identify any appropriate mitigation. As our designs develop we will review the permanent effects on flood risk to determine any requirements for compensation or storage. We are carrying out fluvial modelling of the permanent foreshore works to establish the likely significant effects of the development on the river, and will discuss the findings with the PLA and the Environment Agency. We are also undertaking scour modelling. We do not believe that there will be significant erosion/scour to the river bed around campsheds, however our design incorporates mitigation measures to manage any permanent effects of our works on the river.

Our view of the way forward

We received a range of feedback on our proposals for this site, including supportive and neutral comments and objections, issues and concerns. We took all comments received into account in accordance with the requirements of the Planning Act 2008. In light of the feedback that we received, we believe that no new information has been highlighted that would change the conclusions of our site selection process to date. Carnwath Road Riverside therefore remains our preferred site to drive the main tunnel to Acton Storm Tanks and receive the main tunnel from Kirtling Street; and to receive the Frogmore connection tunnel, driven from Dormay Street. Additionally, no new information or issues have been identified that would fundamentally change our proposals for this site. Therefore we will continue to develop the proposals for this site that we published at phase two consultation. The feedback we received included detailed comments on the construction and operational effects of the proposed development and the measures we propose to reduce and manage those effects. Detailed comments were also made on our proposals for the permanent design and appearance of the site. Having regard to the feedback received, we will continue to refine our detailed proposals for this site to improve the design and reduce the impacts on the local community and environment. We are currently considering the following changes to the layout and/or appearance of our proposals: replacement of the proposed ventilation building with a smaller fan structure and filters relocation of the permanent above ground structures to the eastern side of Whiffin Wharf where they will provide a buffer to the safeguarded Hurlingham Wharf, and a reduction in the height of these buildings from 9.5m to approximately 5.5m. This would enclose the plant and machinery (which require 3.5m of vertical working room) and necessary air flow above below the building roof relocation and redesign of the ventilation column so it is also located at the eastern edge of Whiffin Wharf and by the river provision of an area of landscaped open space in part of the western section of the site with a riverside walkway whether it would be possible to make further use of the river for the import of sand and aggregates for secondary tunnel lining in order to reduce the number of lorries on local roads.

In our SOCC we recognised that we may need to amend our scheme following phase two consultation and that if changes came forward we would consider whether targeted consultation is appropriate. We do not consider that the degree of change in relation to this site or the effect on the local community would affect the nature of the comments received during phase two consultation in such a way as to require further consultation. On that basis, a round of targeted consultation on our proposals for this site is not considered necessary. We will progress with preparation of our application for a development consent order and will incorporate the changes referred to in paragraph 10.8.3 if further work demonstrates that this is appropriate. We intend to publicise our proposed application in accordance with Section 48 of the Planning Act 2008 later in 2012. Full details of our proposed scheme will be set out in our DCO application and the accompanying documents.
